you are heavily overstocked.
fish never stop growing.
that 55 isn't big enough for any of those fish for life even if they were kept singularly.
it's cruel to keep em in a tank that small. sure you've heard this before but that's like keeping a german shepherd in a crate for it's life.
on a positive note. it's good that you are over filtered otherwise your fish would be floating upside down however that does not make up for the fact that the fish don't have enough room.
also your fish do look healthy and the tank clean so two thumbs up but you definately need to upgrade or sell some fish
