I'm very new here but have kept Bettas before very successfully. I have a 23 litre tank that has been cycling nicely with 2 loaches and 4 mini neon tetras. Temp hangs between 75-78 (currently 76.5).
I bought a new Betta today, in the store he looked beautifully healthy, swimming inquisitively with no tears or nips on his tail. I got him home and he just won't stop flaring and attacking his reflection on the walls of the tank (specifically the back wall) by the heater/filter. He hasn't eaten, and nothing I seem to do will distract him! I'm scared he's going to stress himself to death!
Is this normal behaviour? I've heard its because he's in a new environment and will settle in a few days, but my previous Bettas have never done this! Help is much appreciated!
(edit) ps. i've tried him with lights on and off, and filter on and off! nothing seems to be helping!
