My roommate Joe wanted me to ask you guys about his snails. He has a red belly Parana tank with 3 red bellies, a Plecostomus Catfish, and a pike(They get along fine....so far.). The problem is he’s put probably 8 snails in there and each time they die. There antenna kind of shrivel up after a day or two and they start coming out less and less. He tests the water every other day and everything seems fine. The ammonia is a little high but it’s coming down and the water is clear. We haven’t seen the Parana or the pike show any interest in them so we don’t think it’s that. Anyone have an idea why there dropping dead all the time.
