I currently have 3 various gobies, 2 blennies, 1 damsel, and 2 clowns (and 3 minnows I forgot about) in my 90 gallon. Tank is 8 years old but has gone from a puffer tank, then a toadfish tank and now just the small stuff because I just started keeping corals around 6 months ago. The clowns stay in the corner. The Blennies and gobies all stay on the bottom under rocks or in cracks. The damsel has its spot onset my big rock. And the minnows ride the current at the surface unless I’m feeding. My tank actually looks empty and there’s tons of empty space. I’m thinking of adding a medium sized fish that won’t outgrow my 90. Considering a one-spot rabbitfish or a couple different smaller tangs but I’m not sure on either. I have lots of clams, crabs, snails and shrimp in my tank also. It would be great if the fish I add didn’t eat my inverts, but it’s not a tragedy if it does because I have so many. Maybe too many…..

Looking for opinions on whether either of those fish are a good idea. Or any other fish I haven’t thought of. I considered a puffer but I think the feeding habits of a puffer would add a lot of extra cleaning and I’m not sure if they nip corals either.

I really liked some of the wrasses but that was my only drawback.
