SOOO I caught him at it again, after a good month of not touching his tail I saw Aquarius take a big bite out of his tail and now he's missing a chunk. I threw him into a hospital tank with some AQ and stresscoat to help it heal again but WHAT CAN I DO TO STOP HIS TAILBITTING???? It started perhaps two months after I first got him and then I got an ADF and added him in the tank, the tailbitting stopped for a month and then it started again so we rearanged his tank and it stopped for two months, then it started again but we were moving to another state and so we moved, set up his tank and it stopped. Now it's started again today and I am getting sick of watching him turn his beautiful tail into a mess. What can I go to stop him from doing this? Is it a boredom thing? Do I need to change his environmental constantly and add new things?
Tank: 5 gallons (cycled)
Cleaning: Twice a week, 2 50% water changes
Temp: 78-80 (I have a heater in my room so the tank warms up to 80 at times)
Tankmates: ADF, male Bilbo Froggins and moss ball
Decor: Two caves and 4 silk plants plus the moss ball to help keep water quality up.
Feeding: 4-5 pellets twice a day, Wen fasting, once a week frozen bloodworms, once a week live brine shrimp.
Filter: baffled, low flow
Nitrate: under 10, mine starts at 10 but the orange is too light to fully be ten so I guess from 5-8, tank was cleaned just yesterday so....
Anyone know why he attacks his tail?
