My problem is that I have two bettas already, and ended up getting one guppy that had been caught in a plant. I had to put the guppy on one of two sides of the divider, and the betta and guppy are ignoring each other right now. I have a baby betta that needs to go into the tank when it is a bit bigger. Would it be better just to run and get a critter keeper for the guppy and get two more guppies to keep him company? I have a spare heater for them if that is the case.
