Fishy Fish

[nmonks]

Quite correct. It's on p 279 and 317 of Baensch vol. 1, for anyone interested, and on Fishbase here. It's a characin (i.e., a tetra) not a killifish. Needs soft, acid water. Similar to the better-known Crenuchus spilurus, a close relative, in basic care. That's a nice specimen in spawning conditon. The average aquarium specimen kept in a tank with busy tankmates and hard water doesn't look nearly so inspiring.

Poecilocharax weitzmani, possibly.

If it's a charachin, where's the adipose fin? Even the BIG characin has one.

Nice fish anyway!

Not all characins have the adipose fin. Take Copella arnoldi (the splashing tetra) as an example. No adipose fin. Nor do many pencilfish. Conversely, there are fishes that aren't tetras that do have adipose fins, many catfish for example. We need to be careful about taking "rules of thumb" printed in aquarium books and assuming that they're hard science; they're not.

now that I look at it....

It has the blue and red of a cardinal tetra....

Fair enough, just i always thought that was the common denominator. But i guess there is always variation in any species.

I always like the fact that a neon looks like a micro phirana and vice versa.

I think the common name is the Black Darter Tetra. Found on www.thegoldfishbowl.co.uk
