Acestridium dichromum aka "Green Farlowella"

[Quixotic]

Anyone has the book, Baensch Catfish Atlas, Volume 1 by Hans-Georg Evers and Ingo Seidel? There is mention of this fish in there, on page 296 (according to Google Books, but no free preview of the book).

This is the only information I can obtain after some "engineering" work on Google Books.

Newly-captured specimens of Acestridium dichromum are quince-green and just as small and delicate as the other congeners. The Cano El Toro is a typical clear-water river with a low conductivity and undetectable hardness. The pH of such waters is around 5 and the water temperature is usually quite high at approximately 30°C. According to RETZER, Nico & PROVENZANO (1999). it ...

Hmm.. low pH and high temperature.

Well, I'm down to two now...
I suppose I can move them into my L046 tank.
Seems to have the parameters just right for them.
Let's see what happens.
Thanks Quixotic!

Anyone here can read Japanese? This translation is crappy, but here is what I can make out (barely) from this site, http://ybkj.exblog.jp/5445879/ (Google translated page)

Parameters are close to what is mentioned in the Baensch Catfish Atlas, so are some other information, so this site looks reliable.

pH is 4.5 to 5.5
Water temperature: 25.0 to 29.0 C

It is mentioned the fish can be collected from most of Venezuela, Orinoco tributary of the Rio Meta near the entrance to the Rio Casiquiare, Rio Negro tributaries, Rio Amazonas and Rio Atabapo and Rio Sipapo.

They also mentioned that they are fed and eat brine shrimp(?) but no other food. Are they eating anything in your tanks?


Aside from the Japanese site, differences between A. dichromum and others are mentioned in these two available online papers below if anyone is interested.

Neotrop. ichthyol. 2007, vol. 5, no. 4, pp. 429-434. (Description of A. triplax, the Sexual dimorphism part may be of interest, perhaps applicable to A. dichromum as well?)

From what I know, they'll do well in colder water around 25 to 27 dergee C.

Mine was doing ok until one fella kenna stuck in the IOS inlet !.

Bro what do you feed them with?

I found one more dead yesterday night. This always happen when I stay over at my gf place for a night

Quixotic,
Man, you can search for Japanese too!

hmm... I did try the BBS.
They didn't really take to it.
But I will try again.

So far I feed mine with crushed spirulina and algae wafer tabs.
I might release them into the main tank again to see what happens.
Hopefully they start foraging.

[celticfish]

Well, I'm down the the last one.
I tried some crush carnivore tab.
Hope it survives...

celticfish, you are left with a sole survivor?

How about trying some tubifex worms? It works wonder generally for any picky/choosy fish.

Have you guys tried cucumbers? I once have a L236 with sunken stomach which refuses to eat anything. Till one day I decided to try cucumber, & it started eating. When it starts eating & gets back to health, it will slowly accept dry foods. Maybe it'll work on your fish. For what i know these catfishes can't resist those cumcumbers.

[celticfish]

@ Ah ZhaN,
These guys are a little small so I didn't dare feed tubifex.

@ RHX,
Cucumbers? Hmm... might try that.

So far he looks okay.
But its tummy seems to get filled and go sunken... not a very bright future...

[Ah_ZhaN]

Hi celticfish,

Don't worry, even one of the smallest fish I've kept, Indostomus paradoxus, is capable of swallowing tubifex worms.

I'm not too sure about cucumber, most of my vegetarian aquatic faunas don't really fall for cucumber at all. You can try zuchinni instead, which has softer flesh and easier for fish to consume.

All the best,
