when my guy was little I would set up fake plants above the water and I would put crickets on them to feed him. It was cool watching him jump out and get the crickets off the leafs. I stopped this when he got about 12". Now he gets fed silver slides, tilapia and krill...he is currently 22". he jumps when I first drop the food in, out of excitement to get the food first before my other fish, but I dont feed him "outside the water" like I use too. I cut that habit when he was young.
