I agree with the above statement why even give them feeders if theyre on pellets maybe add a little variety to their diet maybe some frozen krill or brine shrimp or store bought shrimp works well you could also try chopping up some tilapia fillet and feeding it to them but Id stay away from feeders just my two cents
i have given my jaguar feeders [platies] from when they are 1.5 inches. the feeders were bred by me. my jaguar did not eat pellets so i have to give feeder or earthworms.
