I have had a tomato clown in a nancube 12 for the past year. Since the clown was solo for a year I figured it had turned female. I upgraded to a nanocube 24, and figured I would like to get her some company. I went to Petco and got the smallest tomato clown I could find. I tossed it in the tank just to see what would happen. I figured I could pull him out at the first sign of fighting. To my surprise he went right over the female and stated hanging out. Its been 2 days and they are never more then a few inches apart, seem to sleep together, could it be this easy?
