I had to start treating for ich a couple days ago I was using tetra ich guard. As of today none of my cichlids are eating I tried a morning feeding after noticing they didn't touch the food I immediately did a 50% water change and replaced the carbon tried feeding again tonight and a few of them ate but very little they're still swimming normal but they normally group together when I open the lid now they all hide in the caves when I get near the tank any thoughts
