I was thinking of setting up a 20 gallon long aquarium and breeding bristlenose plecos and kribensis cichlids. I thought I'd divide the tank in half and on the kribensis side I'd have a cichlid stone and some java moss, maybe even some dithers. On the bristlenose side I figured I'd have a piece of driftwood and a large cichlid stone. I plan it to be bare-bottom and I'm not to sure on filtration. Also, would it make more sense to not separate them and just loose a few fry? Thanks.
