I took some more photos of my fish this evening and this is, I think, the best of them. This is a brilliant rasbora, (Rasbora einthovenii) and they are a good fish to have in a community aquarium. These are about three inches long and quite lively, especially at feeding time. Getting a good picture is made more difficult by their almost constant movement from one end of the tank to the other. I got this one while he (or she, I really don’t know) was making his u-turn at this end of the tank, above the brick that is the only decoration. I really need to get a bit more stuff in there for them to swim around.
Update: I initially labeled this picture as a brilliant rasbora but looking at it again, that’s wrong. There are rasboras in the tank but they are smaller and have red at the base of their tail fins. This is a Siamese algae eater, Crossocheilus oblongus. Sorry for the confusion.
