so many things wrong as pointed out before no 12 inch bass in a 55 gallon tank big no no. I see no red ear sunfish only a bluegill and a hybrid sunfish. Mixing tropicals and natives is almost always a bad idea.
Yea that turtle looks cute now till one morning you wake up and a chunk of your fish is in its mouth and you got bluegill swimming around in circles because the tail is gone.
Bluegill and that hybrid will get to big for that tank and the pleco is already to big.
so for advice i say GET A BIGGER TANK!
