I am cycling a 25 gal aqueon with 3 Cory cats. 2 juli and one pepper. This is week 5. I have two aqueon filters running. I understand that my filtration is more than sufficient, but can't remember the filter specs. My tap water has .25 ammonia. I've tested daily and changed water 25-50% daily, or every other, and used prime. I've never noticed any big ammonia spike yet. My pepper Cory is floating on its side. Thought it was already dead but it swam off and behaved normally for a little while. I changed 50% water this morning. He is floating again now. I touched him and he swam off. Can he be saved? I'm feeding shrimp pellets.
