I have tried everything to get my 2 senegals to eat market shrimp.I have tried mixing them with krill, defrosting them in tank water, in a bag floating in cold water, with the shell and without the shell and I have even cut them into bite sized pieces. I want them to eat the shrimp because it's cheaper than paying $5 for a little 5oz krill pack. Please feel free to tell me what I'm doing wrong.
