My wife and I have experience with fish. She has much more expiernce than I do. We setup our first tank together today we have a 29gal tall eclipse with a biowheel filteration system, we used cycle to balance the nitrates and nitrites which worked wonderfully. We put our first fish in it, a black ghost knife fish and he is still feeling out every nook and cranny in the tank. Ill put up some pics soon he has an awesome white stripe on his head. We were wondering if anyone would have any advice on fresh water butterfly fish and oscars providing that they are about the same size when introduced to the tank will they be ok or is it a bad idea. If anyone has any information or expiernce with this it would be a great help. thank you all much hope to hear from you fellow fish enthusiast soon.
