Hello I have a quick question. I am treating my 75 gallon tank for internal parasites but I was wondering if it is safe to keep the bio wheel filters in while treating the tank. Also do bio wheel filters have carbon in them?
Hey I have a all female cichlid tank with GTs, an Oscar, Jack Dempsey etc. all getting along fine. Just wondering which is less aggressive, a female flowerhorn or a female red devil. What do you guys think?
