Tough to tell at the best of times, not the best pictures either. I wouldn't argue with your early diagnosis at this point in time. I have Bifa that looked very similar to that as well at that size though
hey what's some really cool exotic fish like arowanas, peacock bass, snake heads, bowfins, etc..? if you could tell me some id appreciate it.

Blue/green is the general color. Even in the best of pictures these fish wont look much different. Theres a slight bit of red as well. My other guess would be guttulatus possibly? Is there any reason to count them out?
