Is puttin a freshwater lionfish in the tank with a stingray a good idea, with the lionfish being venomous fish. im thinking bout buying a freshwater lion, tiger datnoid and a fire eel in the next few weeks to complete my tank. this will be my second fire eel the first one died from ick, i wasnt sure how to treat the tank with him being a soft body fish. but any who please let me know what some of you guys and gurls think.. thanks in advance
