I've posted a while ago that he has bloody fins (which did not get better) and now he twitches every now and then! What am I doing wrong? There is filmy stuff on top of the water, never had this until I got the heater.
What do I do?
Water changes: Every other day 25% (added water conditioner)
Tank: 2 gallon
Heated: Yes (77-79 degrees)
Changes in behaviour: Twicting, Bloody Fins, and Darts around the tank.
Tested Water: No
If you have any advice please help me! I don't know what to do. :/
