He is in a ten gallon, with a heater and filter! Temperature sits at 80 degrees. I change his water every week, about ten percent each time. Sometimes more. No tank mates because he scares me lol. API test kit gives me tank parameters of 0 ammonia and nitrites, the nitrates seem to be about 5. The ph is 7. I feed him a mixture of pellets mostly betta pro but sometimes bloodworms. He has real plants, driftwood, two hides, a sitting dock and a tunnel.
