Actually, I am the LFS.
Most wholesalers don't feed fish while they are holding them to sell. Fish eat...poop in bag during transport...cause ammonia in bag...fish dies. So the way around this seems to be not to feed the fish. They come to us (LFS) in less than perfect condition. Getting them to stay alive, then eat, and show good signs of health is a lot of work sometimes...especially with more sensitive species, but worth while in the end.
I can tell you that they are far less now than they were only a few months ago.
I fed them this morning, and again this evening, and both are hanging out together for most of the day, and both are eating like champs. I will probably hook up the auto fish feeder to feed a couple of more times per day when I get them over to accepting pellets. As of now, the only thing that seems to interest them is mysis.
