Can anybody id this fish

This could be an Enteromius of some sort, comparing it to other pictures and with my encyclopedia of freshwater fish, but I'm not entirely sure.

@CheeseChameleon2007 I'm not certain what this is, but it is not Enteromius. Looks more like a predatory type characin to me. Doing some more checking around.

Thought so.

I would say the tucan fish (Chalceus erythrurus). While the belly is swollen, the rest of the body fits the profile perfectly. The pattern makes me say that it is species erythrurus and while I'm fairly sure, the best indicator is still the tail colour which is absent in this picture. Differences between the Chalceus species are not always clear, but this is the best option.
