I recently sold my large blue line trigger and I must say my 230g folwr tank looks empty! Although really it's not. I feel the need to fill the space but my other half (Doug) says I'm fairly well stocked and should leave it alone. I figured I'd ask people's opinions on here and see what others think. First I'll start with a list of fish I have (8 in total) their size and temperament.
King angel 8" super mean (will kill any other type of angelfish so unfortunately no other angels for me) also hates rabbitfish
snowflake eel 12" peaceful but dumb and will try to eat small slow fish (tried to eat a 2" burr puffer

and my 4" Mexican rainbow wrasse went MIA but I'm not sure if the eel ate him or if the trigger I sold did, leaning towards the trigger since I've seen the tigger go after the wrasse before)
toby puffer 3" peaceful
clown tang 3" mean
kole tang 4" fights a bit with the clown tang and sometimes chases the hawkfish but otherwise is peaceful
freckled face hawkfish 3" fairly peaceful but was one of the last ones in the tank, tried adding a burr puffer after him but he attacked the puffer

not sure if it was because the burr puffer was new or if he just didn't like the puffer, never bothered any of the other fish not even the filefish which was added after him.
bursa trigger 3" (has been for years I swear he never seems to grow much at all, it's odd) peaceful
filefish 2" peaceful
That's all that's in the tank right now. I have a goatfish 4" that's very peaceful that's in my 80g that I planed on adding to this tank. However I'm worried that he'll get picked on by the hawkfish (similar body shape and colours) and the clown tang (clown tang chases the hawkfish) so I'm not sure if I should try adding him or just sell him. The mystery wrasse picks on the goatfish in the 80g so more aggressive fish might be a bad idea. Although there's a chance it could be fine, you never know. Thought the blue line trigger would eat the filefish but he never picked on him at all.
Fish I'm thinking of maybe adding (just possibilities not for sure going to add any of them and maybe only one or two if I do)
A grouper (thinking v-tail) cause they don't get a large as others, but might be a bad idea until some of the other fish get a bit bigger. Also might be bad cause I think it'd might fight with the hawkfish.
Harlequin tusk fish, but then again maybe not cause of the hawkfish. Also they have been known marine velvet carriers so I'm not sure I want to risk that
Niger trigger
large non reef safe wrasse
So what do people think?
