In maybe about a year or so i plan on having my 120 (48x24x24) tank cleard out of all my cichlids and move them into a larger tank and i've been looving as some freshwater stingray tanks with bare bottom or just a little bit or some fine sand substrate. I've seen some pbass in with the rays as well. Could i possibly put like one or two rays in there with umm 2 P.bass? I'm thinking of moto rays. Any one have any info on how to keep them or pictures of you setups. Thanks
