This just started to happen, my perc started to use my GSP like an anemone. Should I be concerned?
edit: err its really late I mean GSP, although the idea of a perc using a GPS to find his way around me tank makes me laugh...
It's not unusual for clowns to host corals. Mine hosted a torch coral. I don't think that it will harm the GSP, but it might try to bite you when you frag it.
