In a 55 gallon, I raise them to a good size and sell them at club auctions. It helps me pay for fish food. I last sold a group of 6 1 inch long ones for $8. I will be returning to that club to auction some more in October. I am also signed up to supply about 15 or 20 to a local nursing home where my club is setting up a display tank for the resdidents to watch. The place is just too darned sterile looking and has no life to it. A tank full that looks like this will help spruce things up a bit.
The picture was 2 months ago when they were only about 1 1/2 inches long.
