Hello, my husband got himself a 5 gallon hex tank, it's filtered with a heater set to 80* and he just got a Betta. His Betta seemed sick with a fungal infection when he got him, so we added 1tsp per gallon of salt to the tank, then slowly acclimated the Betta to the new water as suggested in the forums before putting him in the tank. It has been a few days since we got him, and he has only gotten worse, so this morning I put him in a 1 gallon QT tank so we can watch to see what's wrong a little easier, and hopefully treat him. I have my own Betta in a almost cycled 10 gallon tank, who seems to like his water best at 80* and he is thriving as usual, so we chose 80 for the 5 gallon tank since my Betta seems to do best at that temp, but the heater is adjustable.
