Yes, they are very well feed.
They were a lot larger when first put into the tank but have slimmed down extensivly since then. The smallest of the three is by far the fattest since he is still adjusting to haveing a constant food source in the tank with him at all times. I have droped the temp a few degrees in the tank and limited the amount of food for the winter so by summer they will half the size you see here. This has worked very well for me in the past and when spring hits they grow like crazy especialy once the summer months roll around. Aslo just measured the fish, the largest is 3/4 longer, and the samallest Gar is an inch longer from last months measurements. Have not gotten a measurement on the middle sized Gar as he hangs out in the back of the tank as of late.
