shes kinda aggressive so im more worried she'd hurt him if it came to that.especially once she figures out he wont actually do anything..red devils are pretty smart.my pair tries to formulate a strat to kill the convict fry targets in their tank.they always fail since hes pretty fast but one will be on one side to flush him out while the other is on the opposite end lol neat to watch..they also shake their heads at me if they see me get a net even for another tank since ive used that plenty of times to take their fry out from them
