So i got these 2 Helfrichis last month. They have been doing great despite the losses of some corals. Anyhow they have made a small cave in some LR. They always sleep in the same hole right next to eachother. Today when i came home i only saw one Helfrichi out and about. This is the larger of the two and has some frayed fins from establishing territory with a coral beauty, yellow tang, and clown. The smaller one is inside of the cave. I thought maybe it was getting picked on but its fins are fine. I fed brine shrimp but it stayed in the hole while the other guarded outfront. When some brine floated past the hole she would poke out and grab it without ever leaving the cave. This leads me to believe that they might be a pair. Is she guarding something in that cave? Has anyone had experience with breeding Helfrichis? What do you guys think?
