I'll take new pics of my setup tonight, it's a divided 20 gal long. The boys went in last night! I cycled the tank for a week with 10 gallons rain water, 10 gallons stress coat treated tap water. Placed two goldfish in it and let it sit. Last night I added the heater and raised the temp to 80 degrees (dropped it to 78 today just in case, I don't want that heater cooking my bettas!). Otis is in the middle, my g/f's crown tail is on one side, my crown tail is on the other. He sees them and shows no interest! They see him and lock on. They haven't flared at him but they've postured. I don't know, maybe these King bettas are just naturally easy going. He will come up to my finger looking for food but my g/f went to feed him today and he shot to the bottom of the tank and hid! very odd LOL.
