Ive done some searching and I cant find a difinitive answer to what Im looking for. I have a pretty basic set up, 150 gallon with a 5" retic stingray and a 6-7" silver arowana. Now, Im curious if i go buy a fire eel, will these 3 get along in your opinions?? My wife says yes but Im a little hesitant. I do have 1...yes 1 feeder in there that has survived for about 6 months, so I guess if he survived I should be good right???
