Anyone have any experience with keeping a full grown fahaka in a tank that is only 18 inches wide? When I was looking to buy my fahaka two and half years ago I had a thread going discussing tank size. The general consensus was that a 120 wold be adequate. Now that she is 16 inches, I do not think the tank is big enough. I consistenly see 125s and 150 gallon tanks availible. I have not seen too many 180s. Would a tank two inches wider then my fish be alright? Right now I am testing her out with tankmates. She has not killed the three bala sharks yet, so ideally the tank would be roomy enough for some "friends"
