What to get next?

I hope you catch the dotty back, if you're having troubles drain the tank. Since it's only a 33 g you can drain it down fairly easy with a garbage can, then remove the rock work and catch the fish. He'll definitely be better living alone in your sump. Better do it soon before he kills the other 2 fish you have.

I learnt my lesson years ago when I kept a strawberry dotty back in a 65g, had to rip that down to get the fish.

Also I bought an accessor that the owner warned me was agressive but because I had bigger fish I thought it would be fine. Nope he had to be sumped aswell.

I like royal gammas for colour, also leopard wrasses, fairy wrasses, percula clowns, and maybe one halicrocheus wrasse. That maybe too many fish for a 33g but see what fits your tank and tank mates. If you do get fairy wrasses be sure to put a net lid or you'll find some dried anchovies on your floor.
