yellowstripe threadfin bream (Pentapodus aureofasciatus)

This does not look to be P. aureofasciatus, but rather P. emeryii?

That's the species of the signage at the tank.

@Sicarius - the pictures following this link Pentapodus aureofasciatus are similar to my picture. P. emeryii shows another kind of tail.

@wstefan You are right, I was too fast to respond. I looked into these species right after making this comment. What it could be is P. caninus, which is barely distinguishable at this age. I'm curious to see what this fish will turn out to be. P. aureofasciatus is pretty rare and I have encountered a true one only once before. I hope it turns out to be this species eventually.
