Difference is size and aggression. I think u already know. Jaw folds are same. But pores can tell the main difference. Curu have 4 patches of pores along the bottom jaw and Aimara have single pore running along the jaw line. Lateral line scale count is also different.
I wasn't posting for identification, if you read what I wrote I said my old curupira.....so obviously I posted the pic for you to compare to.Plz do not just post random pictures for indentification within this threat, better open your own.
Can you show me on the first 2 pictures where the pores are so i can see the 4 for myself? Also a juvenile aimara pic with only one pore would be awesome tom be able to compare.
Mine still showed dark colors on light substrate, it changed with its moods. Lol a couple times I thought it jumped out because it would blend in with the black background.imo for the light coloration . it can be how your tank set up is. dark base tank. dark base fish. My curu is all black cause how dark my setup is(black back and sand. When first got em. looked the same as the op's its wass white yellow... but not as contrast. Very interesting curu! gots my attention
Heres mine if you dont mind
