I've got a 55 gallon tank with an ocelaris clown, a midas blenny, a sixline wrasse, and a yellowtail damsel. I'd like to add another fish but am not sure what to get. I was thinking of an orchid dottyback but I'm concerned about compatibility with the wrasse and my shrimp, or maybe a bicolour dwarf angel but I don't want to stress the bioload and I will want to add coral soon. I'd like to get an active colourful fish that swims around the tank. Does anyone have any suggestions?
