Fish that eat aiptasia will put holes in LPS
and soft corals...most likely eat the polyps off of SPS
. Adding livestock is not a solution towards problems in the system. When it comes to the difficulty of copperbands, the difficulty is getting them to and keeping them eating.
I'm not sure why you need to use aiptasia-x daily? It is simply shooting it down their throat and covering them with it. Have you thought of covering their hole with putty or superglue gel? Can you take the light off and burn them with a lighter?
