Well, I'll see if I can help.

The shark-like one is a bala shark.

The yellow and black striped one is a clown loach.

The black one with red fins is red-tailed shark.

The round, striped one is either a neon blue or a powder blue dwarf gourami. (The only difference being one is brighter than the other.)

Of course, angel fish.

The little red ones look like cherry barbs.
