I got my betta fish, Rocky about 8 months ago from a pet store.
He was fine until about a month ago, and I noticed he was a little clampy. He is having a hard time swimming and was sinking to the bottom of his tank a lot. I am in college and he stays home while I am gone. So I cleaned his tank (100% change) and told my dad to try feeding him a little less.
Well I came home yesterday and he is looking about the same except his fins look ragged (fin rot maybe?) So we have a fungus treatment that we got and I have been putting the correct dose in his water.
Today I moved him into a bigger tank (3 to 5 gallons)and made sure to use the water from his old tank and add a little bit more conditioned water. This tank has a low setting filter that I hope works. However, since I have moved him he has been sitting at the bottom breathing really hard. He moves a little but he is still breathing really hard.
What can I do? Is it fin rot or fin clamp? Please help I will do anything!!!
