So i went to a lfs who had some nasty tanks a few months ago. I went back today and the tanks look very good now. I was talking to a employee about the red tail barracudas they have. They range from 4-7 inches and i thought about buying one. They are $25 and i was going to trade in my 2 hujeta gars for one. I thought the barracuda would be better off with my wolf fish than the gars... Does it sound like a good idea. The one i want is 7 inches and seems to like being alone as he chases the oscars in the tank...
