Have a 90 gal. reef tank with Blue Tang, 4 Cromis, 2 fire fish, engineer goby (convict bleeny?), hermit crabs and turbo snails, mushrooms, button polyps. Just got 2 tomatoe clowns and would like to know if Seabae or bubble tip would be better for them.Also concerned about the engineer goby digging around them, he is digging under all of the live rock and hope he wouldn't dig around a nem???
