What pygos are the thickest in order? I was just curious because my piraya is quite thin compared to my other pygos at the same length.

I feed all my p's the same food. I rotate beefheart, chicken heart, krill, shrimp, smelt. But a good portion is beef heart. My other pygos are alot bigger than my piraya.

It can deal with the individual fish. This is mostly an opinion topic so you will get varied answers

I think Cariba are thickest for fish of the same size, followed by Piraya, Yellow Natts and then Red Natts

it varies on the individual fish. caribe and ternetzi are the 2 thickest from my experience. they are very close in size.

piraya and natts are also very close in size.

Anything is possible but as i´ve read the order is as follow: P. Piraya, P. Cariba and finally P. Nattereri (including Terns)!

From my personal experience limited with Piraya though, Cariba seem to be more stocky in build at adult hood than the others, and piraya seem to be more elongated, very slightly with both compared to Natts, but I feel it is noticealbe

From the comparisons and relationships (Fink 1993, 1997), the species are quite similar. Body shape is stablized allowing recognition of Pygocentrus species, however, the only recognizable differences pertain to color pattern, size (as in P. piraya large size and rayed adipose fin), with color being variable like those pertaining to P. nattereri which water effects coloration and pigments. In most of the differentiation among the species, nattereri is most similar to cariba. As for the rest of the remarks pertaining to thickness no way to quantify it since it is variable according to diet and ecology.

I have two piraya that are the same but one is thinner than the other. one is about 1to 1.25inches and the other is close to 2 inches. 4 cariba that are about the same size and they are different in thickness also. The thicker ones in my tank iv'e noticed eat more.
