That kinda looks like a Neolissochilus Stracheyi. I have 12 of the copper version Neolissochilus Hex.
Haha. I just googled it and found one that looked similar and pretty. I don't profess to be an expert on these guys though.

Is the body plan of the tambroides closer to that of the putitora? If so, that would make it a very nice fish. I love the aggressive, riverine look of the putitora and would love to have one someday.
