The green fluid usually means parasite destroyed an organ

Very nice fish, but hope you didn't overpay for it, thinking it was something else.

This one is an aimara , the others are not.

thanks, i am not overpay, my exporter agreed that it might not be aimara because he get in small size, but is same river with Aimara, so he will bill me only for Mala or Lacerdae or black. will wait it to grow a bit and decide the price later.

Hi, thanks for point out, do you have any idea what type is the other small one? will it also grow big size?

They look like mala. Hard to say if they will grow big unless you have a precise location on their capture?

lacerdae is restricted to the south of South America. In Venezuela there are are 3 sp of hoplias the mala and curupira and aimara of course. In Lake Maracaibo and nearby drainages there is another species similar to malabaricus that is called Hoplias teres. But the whole problem referring to malabaricus X teres has not been accessed yet. so the best way to check if it is a mala or a curupira is to check the position of the dentaries (parallel or converging). however mala usually have a black spot on the dorsal part of the caudal peduncle.
