We have a 55 gal reef tank that we plan to have heavy with coral. We have four small fish 1 Tail spot Blenny, 1 Green clown goby, 1 wheeler goby, 1 green barred goby. They get along well and in 1/2 the tank( the side with more coral) we want to put in 1 royal gramma , maybe a small group(3) of catalina gobys. We would also like some kind of hair algae eating fish that will be a larger show fish that will stand out and free swim in the tank rather than find a cave to hide in a pop in and out. It is cute to watch the little fish but we want something that will be easy to see and active but NOT A BULLY OR A CORAL NIPPER!! :strooper:Any suggestions would be awesome?! Also we want to be sure we aren't over loading the tank with too many fish for a heavy coral tank.
