just noticed when i got home from work today some bright neon yellow looking spots in my tank. noticed it mainly around a piece of rock that has bunch of zoas on it but there was a few little specs about 2inches away and then again around four inches away. also notice that a shroom nearby was all closed up which is never really closed except at night and few other pieces were closed up that are usually always open. did my patch of zoas squirt something out and should i move my other corals away or should i pull them out of my tank and quarantine them. i never seen this before and it really glows but has me worried. any ideas?
