Okay there are some good ideas. I'm now thinking of a large school of rummy nose a gang of panda cats and or sterbie cats and a pair or trio of bettas to watch the Pantodon bucholzi butterfly fish. The butterfly is the only one I have not kept before. I hope it is not to hard on the rummys. Then with plants I think I want one to float with big leafs, some Anubias and some other plant to be a clean filler that offers little or no cover at the base. I want lots of plants but not so thick I cant see the fish. I would also chuck some plecs in there too. :bounce: or maybe I should just get some big fat arse fish and call him bud. How long could a arrowana be in a four foot tank for? I'm guessing only a year or so .
