Just wondering. I have an 8 inch ropefish in a 10 gallon tank, and he definately needs more room. I am going to get a larger aquarium very soon. However, I was wondering if a plastic tub would work. I know they can occasionally leach chemicals long term, is there any safe type of tub that doesn't do this? Reason I ask is they are cheaper, and much much easier to find. Also, is there any way I could treat my ropefish since tomorrow is Christmas? :;shat Any food they particularly love?
