Thank s for the input. I used my heat gun before I hit it with the hair dryer and it was 80 degrees, so I hit it for about 10 seconds and the right into the tank. I'm going to try a little warmer next time. The one I fed this week was the smallest one I had. I planned to get rid of those first, but if I can find a reliable source for some a little larger I might go ahead and get some and feed the few I have that are over 20 grams. I didnt buy very many of them so it's not a loss if I don't end up using all the ones I have left. I only spent $20.00 because I know at his size he might be ready to move up to smalls soon.
