My betta started to lie on the bottom of his tank last night about 10 pm. So, I checked the nitrite level and it was .25. So, I changed his water, added aquarium salt and API's Stress Zyme. Still no change. I noticed that he has a weird behavior. He will lie there for awhile, then swim around the tank fast for like 2 times, then get some air and rest again on the bottom. I have had him for about 2 1/2 months. He is in a 3 gallon, bio-wheel, carbon filtered tank. I clean the tank about 25% every week. Last night I cleaned it about 50%. He was eating regularly, but I didn't feed him yesterday. If I come over to his tank to look in, then he will get up and come over. Last night while cleaning the tank he was his usual self--swimming around investigating everything while I cleaned it.
Could it be chemicals from the rocks I have in the tank? I got them from PetCo? They have an iridescence on them. I use spring water in my tank and water conditioner, and aquarium salt. 83 degrees aver.
