Pseudomugil sp.”Aru”

I hope all of you are having a great day!
I’m here to present another relatively new Rainbowfish of the Pseudomugilidae genus! It resembles a blue-eye from the grouping of P.gertrudae and P.paskai, and it goes by the name of Pseudomugil sp.”Aru”.

I would like to once again give photo credit to Hiroyuki Sasaki, a well-known photographer of smaller fish here in Japan, and the fish of which the photos are of, are from a shop by the name of “Tropical Garden”.

White-finned Aru Male

These beauties relatively recently have been making their way into the hobby via Indonesian distributors. They are at least claimed to be collected from the islands of Kepulauan Aru, which is a part of Irian Jaya, New Guinea. Which specific island of the Aru islands I have no knowledge of.


These may be a variety of gertrudae, that is still yet unknown, but it is a likely fact, being that the original P.gertrudae were collected from one of these very same “Aru” Islands, known as “Terangan” island. When it comes to localities of the same fish, Rainbowfish in general are known to vary greatly in terms of color, finnage, and patterns. Although there are usually some characteristics which are consistant throughout all the locality types. For example, in this case, if it were a P.gertrudae variety, it shares the black-spotting on the fins. Then again, so does P.paskai but that’s a whole other species of Pseudomugil. The Rainbowfish groups is quite a varied group of fish.

The most defining characteristics of P.”Aru” is that #1 the anal fin’s 3/4 rays are extended, creating a sickle shape. #2 is that all of the fins (with the exception of the pectoral fins) will either have a white-hue or an orange-hue on their edges. The pectoral fins of both the white and orange varieties exhibit a deep orange color at their tips. You can clearly see these differences in the 1st photo posted above of a white-finned male, and the photo below of an orange-finned male.

Orange-sickle male

The females, as with all Pseudomugils are quite drab compared to their male counterparts. The eyes are still blue, but the body has almost no color, finnage, or patterns, resembling the males.


I haven’t had any experience breeding/raising these, but from a friend of mine who has worked with them, they really pose no serious problems. Relatively easy to both keep/raise and breed. Of course with most Pseudomugils, they will do much better in groups and aren’t very aggressive, with the exception of the males sparring with each other.

I hope you enjoyed this post! Another on a relatively new and beautiful Pseudomugil!

Pseudomugil sp.”Timika”

Hello Hello!
I know it’s been quite awhile! I was on vacation back in my home state, but now that I am fully relaxed, here is another post! I haven’t done a fish post in quite some time, this one will definitely drop some jaws!

One of my favorite genus of fish is Pseudomugilidae, more commonly known as “Blue-eyes”, from the group of fish called “Rainbow Fish”. Most originate from Australia and surrounding island nations such as Papua New Guinea, or Irian Jaya. These are small fish, but they pack a punch in terms of color, pattern, and finnage! The specific one that I will be covering today is known right now as Pseudomugil sp.”Timika”. In all honesty I have not seen a blue eye this gorgeous in a looooong time!

Credit for all these photos go to Hiroyuki Sasaki, a well-known photographer of smaller fish here in Japan. The credit for the fish goes to the shop “Tropical Garden”.

Males sparring

These small fish (the ones in the photographs are just under an inch long) come from Irian Jaya, the Western neighbor to Papua New Guinea, on the island of New Guinea.

In terms of sexual dimorphism, the males are much more flamboyant than the females, as you can see from the picture below. The color and finnage are much more boring/drab compared to that of the males.
Female “Timika”

These Pseudomugils began being imported into Japan (at least) 1 year ago. I have no experience raising or breeding these fish, but I have heard that they are relatively easy to keep. They will do fine in pairs, but they do just as fine, if not are more comfortable when kept in groups. They aren’t overly aggressive towards one another, although the males will often spar, no “real” damage is done to one another.


I hope you all enjoyed this short write up on a new GORGEOUS Blue-eye, hopefully this genus of Rainbow Fish will become one of your new favorites!
My next post will most likely cover another Pseudomugil. I promise you its another eye-catcher!

Ivanacara Adoketa

Hello all!
I know it has been a loooong time since my last post, yet here is another, and I hope all of you had a great Christmas and New Year!

This post will be a short one about a jewel of a South American dwarf Cichlid called Ivanacara adoketa. This fish recently was placed into it’s own genus within the last few years, when previously it was put under (it’s now closest relative) genus of Nannacara. Ever since I found out about this fish from a close friend, I’ve been on the lookout for wild specimens of it. Only within the last year or two have I seen a large influx of wild specimens.

I was told this fish is difficult to get a hold of, all the more added to the rarity of this fish. In my opinion, even out of Nannacara, this specific fish is gorgeous, with long and tall finnage, bright metallic colors and eye-catching patterns. There is a catch though, unfortunately, this species is very territorial and aggressive, to males and females of the species alike, if a male does not like what he sees, he will continuously give chase. There is clear sexual dimorphism, the picture shown is of a male, and females are much more drab all around. Like many other South American dwarf cichlids, this one prefers clean very soft and acidic water. This fish can also get quite large (in terms of dwarf cichlids in general) where it can reach a length of about 4-5 inches, the specimen pictured below was about 4 ½ inches long. That size along with it’s territorial behavior, demands that whomever decides to keep this fish, will need to take the “space” issue into consideration.

I hope you enjoyed this short post about the beautiful Ivanacara adoketa, I will definitely try to post more often, but for now, thanks for visiting!

Favorite Hyphessobrycon!

Hello again!
Today’s post will be back to fish, and specifically Characin, and even more specifically, Hyphessobrycon!

Hyphessobrycon are among one of the largest genus’ of the Characoid family. These relatively small sized South American Tetras come in a variety of shapes and colors, but among the huge variety of patters, colors, and shapes, I really only have a fancy for a few of them. For the ones that are pictured below, the males generally will have longer fins, and be more slender in shape, whereas the females are more plump and have much shorter fins.

My taste in fish usually has a good balance of two features in fish: color and finnage. My favorite genus of fish which have clear example species that fit this criteria for me is the genus Apistogramma. These are small fish, with beautiful finnage and amazing colors.

Nonetheless back to Hyphessobrycon for today!

Hyphessobrycon copelandi
These beauties may not have the most amazing colors, but their subtle red/violet (depending upon locality) colors are made up with their fantastic finnage, the males of this species have a tendency to spar quite a bit. In my opinion the white lining on the fins highlight their most beautiful feature.
Hyph. copelandi

Hyphessobrycon epicharis
This is a relatively larger Hyphessobrycon, the pair that I worked with, were 2 inches long and about and 1 1/2 inches tall. This one definitely fits the color and finnage departments well in my opinion, with red and yellow hues, and tall finnage. A bit more, mellow than the copelandi.
Hyph. epicharis

Hyphessobrycon takasei “Coffee bean tetra”
This again isn’t one of the more colorful species, but the one thing that catches my eye the most, is the large spots on either side of it’s body. Many Hyphessobrycon share this “spot” but the takasei, has one of the largest! It’s just an odd little quirk about this specific species that I have a fancy for.

Extravagant Corydoras

Hello all!
Sorry I haven`t kept up with my usual once a week posts, but today there will be one about one of my favorite genus of catfish, the Corydoras.

Corydoras are an armored genus of catfish which hail from streams and small backwater areas of the Amazon river basin in South America. They are a schooling species of catfish that, in the wild, can be found in groups of up to 100 individuals or more. Raising these fish are quite easy, they aren`t very sensitive to water parameters (prefer soft acidic water), although they can be sensitive to water quality. Also when Keeping Corydoras, try to be sure to scrub the bottom of the tank, or if you have a substrate, sift through it to get the detritus out of it, as Corydoras, especially wild specimens, tend to have sensitive barbels(whiskers) and if you let bacteria and such build up where their whiskers are most in contact (bottom of the tank) they sometimes can get infections at their mouth, which can be quite pesky to get rid of.

As a side note: Really try to avoid getting pricked by one of their spines of their 1st dorsal fin ray, and 1st rays of their pectoral fins, of course it hurts, but it THROBS, as I believe there is a mild toxin released from the spines. Trust me I know how much it hurts, it is quite uncomfortable!

Corydoras “Super” Schwartzi
The body pattern can vary quite a bit, but in Japan they rate the quality of this and a few other Corydoras by how well the horizontal lines along the body line up well making clean straight lines. The more straight and clean the body stripes are, the better “quality” the fish is and of course the more expensive it gets. I`m sure that you`ll agree that cleaner lines make a more attractive fish. The sexual dimorphism between males and females is not distinct as both males and females share the same characteristics, but that the females are a bit wider (As seen from the top) and a bit larger in general.

Corydoras pulcher
Corydoras pulcher
This is one of the longer-nosed species of “white fin” Corydoras. The tall cream-colored dorsal fin, with it’s extended dorsal rays is the premier characteristic of this Corydoras. The first few dorsal rays of this fish can get long enough that they will curl back towards the fish, making a small “loop” at the tip of the dorsal fin, seems odd when you think about it, but it is really quite beautiful. The sexual dimorphism between males and females is not distinct as both males and females share the same characteristics, but that the females are a bit wider (As seen from the top) and a bit larger in general.

Corydoras “Super” eques
I don’t believe this Cory gets its due amount of attention, in terms of its coloration. There are other forms (which don’t even come close in color) of eques out there, I like to believe this is the true form of this species. The green coloration is actually metallic (as you can see from the bad over exposure 😛 where certain areas of the green mirror my flash) and that color’s contrast against the orange-red spots behind the head and in the fins are very eye-catching.
Cory Super eques

Corydoras pantanalensis (C5)
This is that extra, AMAZING Corydoras I was speaking of, this is nothing especially new, (once known as “C5), but this is still quite the colorful and attractive Cory. This Cory has a base body color of metallic green but the males have a mottled pattern over their whole body, fins included (the fins can also get quite long also), and on top of that pattern they have a metallic sheen. There is a distinct sexual dimorphism with this fish, when the males are on top of a dark substrate, or in a breeding mood, the pattern becomes really dark almost black, but with the green body color still showing through the pattern and still with the metallic sheen on top of all that. This fish in that situation is quite the sight to see.
Cory pantanalensis male

The females are such a contrast to the males, as they are a bit simple, with the green body color and no pattern, also with most other Corydoras, this sex is the larger of the two.

I hope you enjoyed this post about the a few dwarf catfish of the Genus Corydoras! My next post, in about a week, will most likely be something related to aquatic plants, I am thinking something along the lines of wild Microsorium (Java fern) varieties. These plants took a lot of searching for, and they cost me quite a bit of cash, we`re talking in the 100s of dollars for a cutting, want to see what they look like!? Keep checking back here, Aquatic Quotient or Aquatic Plant Central for new posts to this blog!


Who else loves Apistogramma!?

Hello all!
Today there won’t be any aquatic plants in this post…sorry 😛
Although today there will be a nice little post about a few beautiful dwarf cichlids, of the genus Apistogramma!
This is by far my favorite genus of fish for the reason that they are a small-sized genus of fish, and they hit 2 main points that I seek for in fish, which are a nice mix of nice fins and beautiful color. I’m not saying all, but many fish are very strong in one point, but lack in the other.
I mainly focused upon wild specimens of Apistogramma as I have found those much more beautiful than any aquarium strain. Although generally this brings up a lot more difficulty in breeding and even raising this genus of fish, if you are planning on keeping wild specimens. They are much more sensitive to water parameters and quality when they are wild, and are not accustomed to the aquarium environment, like the aquarium strains.
Check a few of these dwarf cichlid beauties below!

Apisto. Rotkeil
This particular species lacks flashy colors which are a staple of the genus, but it definitely makes up for it with its beautiful finnage, as you can see!

Apisto. baenschi
Previously known as Apisto. “Inka 50”, this is by far my favorite of the “Panduro” group of Apistogramma, mainly because of the tall dorsal finnage. The “Panduro” group (Apisto. martini/panduro/baenschi/njisseni), as a whole aren’t very difficult to breed/raise, they are more forgiving in terms of water parameters/quality.

Apisto. Viejita 3
This is by far one of my favorites! Most people have seen or worked with viejita 1 and 2, both of which are generally speaking red/yellow. This one is unique in that is it as you can see, blue, yellow, and white! Not many people have seen this # of viejita, as it is quite rare.

Apisto. mendezi
This Apisto doesn’t have the largest fins, but it definitely makes up for it with the flashy metallic colors and body patterns. Given the right lighting and water quality, this one shines very brightly!

I hope you enjoyed this post about my favorite genus of fish! I know there isn’t too much information on breeding and raising, but this is a post mainly for the eyes 🙂

Thanks for taking a look!
