The story goes like this: a friend at work tells me " I got this cool looking catfish in my 20g tank. He was just under 2" and now he's just under 4" and I've only had him about 5 weeks. Can you come look at him and tell me what he is?" So I go over and he has what I believe to be an almost 4" TL tiger shovelnose. I tell him that by 1yr it will be at least 12", by 2 probably 18-20", and full grown 3.5-4'. Well he proceeds to net it, bag it, and hand it to me so now it is in my 110(48x19x30). I know he won't be able to stay there long. I've already started an outdoor pond project that was going to be 2' deep at 1200g. I've decided to go now with 3' and 2400g. My only real question is what would be the minimum temp. that the pond would need to be maintained at.
