So I wanted to get a blue fish of some kind to add to the color spectrum of fish in my tank. It's a 35 gallon. Current fish are mccoskes flasher wrasse, bicolor blenny, and an ocellaris clown. I wad thinking a goby if some sort or some other small fish specie. One I've seen that I liked was a lyretail blue gundgeon dartfish. Do u think being such a doctile dartfish that it will be harassed?
