so i was thinking that my betta fish (Igor) didnt like the current so much from my filter...so i did that pop bottle trick thing that somone had shown on here and he seems like that..he is now moving around the whole tank instead of on the side with the least current....but i woke up this morning and he wouldnt eat..when i got home from school his food was still floating..i took it out and gave him a couple more new pellets to eat...its been about 15 minutes now and he is still not eating..i even set them right next to him in the tank so he would see them....he is blue with a little red...and i noticed that he doesnt look as blue towards his face anymore...hes getting darker...what could be wrong with him?
