Earlier I had posted in the Emergencies section as I thought my delta tail male had fin rot. I have not moved him to a QT tank since the damage was minimal. I've been doing daily 70% water changes and have been using AQ salt every other day.
He only bites at night so I've never seen him do it. I first thought his tank was getting too cold at night so I added a Hydor 25w heater and his tank stays at a consistent 76-77 degrees. He stopped, so I thought that was it.
Well this morning I noticed he was back at it. The last time he bit was 4 days ago. How can I figure out what is causing him to bit his tail? More importantly....what should I be doing on a daily basis and for how long to prevent illness?
Some info on his home:
Size: 5 gallon
Heater: Yes, 76-77 degrees
Other: Gravel substrate, no decorations, a lot of silk plants for him to play/hide in. He sleeps in one of his plants.
WC Routine: Right now its been daily 70% changes. Normal routine is 2x weekly. 1 is a 50% the second is a 80% with vacuum
Food: Either Hikori Bio-Gold pellets or Aqeon Betta pellets. Occasional freeze dried bloodworms for snacks. 3-4 pellets once a day in the evening
