Recently moved em to QT with a few other fish in a 20 gallon and isn't eatting any food. I tried nori. Seaweed pellets,mysis. He would just eat the algae off the rocks in my display but now I QT and treating for ich ( had an out breaking in display) any other ideas to feed him what? I dont want to see him die but I think he might if he keeps this up since he has thinned out.
