Could frozen cubes be harboring aptasia? My tank has been pretty much empty and cycling for the past 3 months. I have my clowns in there and just been feeding flakes. I’ve been watching the tank like a hawk because of my last aptasia outbreak. I wanted to mix up the feeding of the clowns so a couple weeks ago I got some frozen cubes from petsmart. My tank has been perfect until today when I noticed 4 aptasia. The only thing different that has went in the tank was the frozen food. Could it be?
