Quick update, heater is in, after tons of adjustment and fluctuations, he is in at 82-84, was flaring at himself yesterday :), now he is swimming around crashing into the walls when I touch the tank. I bought Tetra Aquasafe Plus, is it safe for Bettas? if the directions say 5ML per 10 gallon, do I use 1/2 ml for my 1 gallon? How much is that? One more thing, he STILL won't eat his Tetra Betta Plus Pellets! I tried crushing them, but no avil! Is this normal?
