I feed him about 2 or 3 pellets in the morning before I leave for class (9 a.m.) and then if he only ate 2 pellets in the morning, I'll feed him one more during my break (12 p.m.).
He used to be a hog and never stop eating (this was before I knew that they can be over fed). I only feed him a max of 3 now. But he sometimes won't eat anything at all... like today, he went to get the food but kept spitting it back out.
Also, I cleaned his tank again today and took the snail out (water was really foggy). He seems pretty active in his little temporary cup that he stays in while I clean. But no eating today :(
Oh, and no I haven't been able to get the testing kit yet. I hope to go tonight or tomorrow for sure. I'll get some different food as well.
