I know I need a bigger tank but I wanted to start off small and then work my way up. Not to mention, I have a problem buying fish, impulse buying and then returning them lol. With what everybody is saying, my fish will be around a foot in a year. I still cant get them to eat anything but feeders and I dont want to starve them. They may grow more with massivore pellets and krill or other foods, but im not concerned with them getting huge right now. Now, seeing all the fish people are raising, I decided I wanted to get a red tail catfish and royal pleco and put all four fish ( 1 clownknive, 1 tsn, 1 red tail catfish, and royal pleco) in the same tank. Not my 46gallon! but a much larger one down the road. I want to upgrade in a year or so. If u were me and wanted to have all those fish in the same tank, what size tank would u pick? I was looking at them online and I think a 500gallon would be good. Thanks
