I have a few tanks now and I decided I'd try this forum out to see if anybody could identify this fish. It doesn't have facial stripes like some species have, and no spots on its body, it's more like a faint colored stripe that comes in darker when he gets upset. Normally you can't see it at all, he's a jurupari I'm almost certain of that also not sure if this could be helpful he's about 3 1/2 to 4 inches long.
