Yeah, nice tank but its over stocked.
If thats a Bala it will grow atleast 1' and it needs a minimum of 75Gs.
Is that a pink kisser? If it is, then it'll need atleast 55G's, because it also gets up to about a foot.
Otherwise, you tank looks nice.
I dunno about the bichar though...
That Golden Shark is actually a Leptobarbus Hoevenii aka Red finned cigar shark, they will easily reach 30cm and can grow to 50cm. They are best kept in groups.
