I want to get 3 butterflies for my tank; I have zooplankton, phytoplankton, live baby brine shrimp, frozen mysis, and clams. I will be able to feed them, but what butterflies would you recommend for a reef tank? I don't plan on having clams in the tank but I want coral and shrimp. I want a CBB and two others. LMK what worked in your experience.
