I added some frozen brine shrimp to the trap today and it seems to be working? Well, I almost caught the tang - you know, the one I'm not wanting to catch. He's tried getting in the trap at least 5 times now but he's slightly too big. The Chromis stuck his face in the bottle but wouldn't enter fully which is fine - he can stay in the 75 for a while. One of the Bangaiis is hanging around the entrance chasing the Chromis and Tang away so he may go in? Wait and see, wait and see.
