So, I only have 1 mbuna left and i need more, but the problem is he is 5" and you can only buy them at 2.5" (or at least thats all i can afford). I am thinking of getting a sheet of acrylic from lowes and making a divider by drilling holes and slits in it. I would do intake on one side and output on the other from my canister filter to keep water flowing. Does this sound like a good way to seperate them until they come to size? Is the lowes general acrylic safe for aquariums? Any comments would be helpful, thanks!
