There are 2 species of pink tail chalceus under the same common name.
I have two 7" chalceus. They're characteristics are different. I've looked online and there's 2 pink tail species. I'm not sure which one is which. Can anybody confirm the specie for left and right and estimated max size? Thank u.

One has a round nose and yellow lower fins; the other has a pointed nose and faint red stripe. I have the latter one. I keep one in a 75 gal as they are highly conspecific agressive, so you can either keep one or a group in a big tank.
PTC are surface dweller, and mine has never ventured down for food. Yours are all over the tank, suggesting they are cramped in tight space. They look stressed and I’m surprised they haven’t tear one another up yet.
