So I want to share some experience about training corallivorous butterflyfish. Below are the two techniques I use to get these fkers to eat, be noted that the younger the fish is the easier it is to wean them.
The first way and the way I’ve been having most success with is to tie a clam or an oyster to a piece/colony of dead sps coral. Idk why but clam on the half shell never works well for me in the beginning. The butterflies always run for their lives the moment I dropped a clam in. It works fine after the fish are weaned though. I was able to wean C. baronessa, C. plebeius, C. speculum using this method.
The second method is to use sacrificial corals, by sacrificial I mean you feed them live corals at the start, and then slowly wean them off. I can usually get a bunch of ugly lps for a very cheap price at the lfs since no one’s gonna buy them anyway. Then I give 1 to the fish to feed. The problem with these corallivores is that their feeding response is usually suppressed after collection. So we need to kick start it before trying to wean them off. When the fish nearly finish the coral, I then tie a clam to it (like method 1). They will eventually learn that the clam is food after nipping the remaining coral and taking up the scent of the clam inadvertently. This method works for the more difficult species like C. ornatissimus.
Another way for non-feeding individuals is to use bbs. Somehow really small corallivorous butterflies go crazy for those, I’ve had a C. lunulatus and octofasciatus nearing starvation resumed feeding by offering bbs. They went nuts the moment the bbs hit the water.
Here’s a video of my ornatissimus feeding on clam and corals.
