My son got a male betta for his birthday in November. He came with a small starter kit, you know the little plastic 1 or 2 qt. bowl. The first month he was perfect! Always wiggling when I came to feed him. Never had a heater or anything( just now reading that he needs one!). For about the last 3 weeks he has been laying sideways. He can swim fine when he feels like it, but he looks like his breathing is labored. He isn't coming to the top to eat like he did in the beginning. So I went to the pet store after reading some things on the internet. I got some new water conditioner called betta bowl essentials. I bought a live plant to absorb the nitrates, also got some antibiotics (neomycin?). I have been cleaning his water, put new rocks, all of the above for about three days, but no change. Also have been keeping a lamp on him to warm the water. He does not appear to have any ich on him. I need help! Thanks!
