This makes me wonder about feeding fish actual shrimp, like I would eat, in my shrimp cocktail. Cut up into tiny pieces, I wonder if they'd enjoy it... sure it'd cost more and be a pain, but regardless.
Well I feed my fish feeder shrimp and glass shrimp and they LOVE it. My angle hunts them down and eats them with 1 bite. My clown loves it as well. He'll grab one and get it partially in his mouth and keep spitting it out and eating it again until he eats is completely.
I try not to feed them the same thing all the time, I have Formula One & Formula Two pellets, along with Red and Green seaweed and Cyclo-Peez. Then I have brine shrimp and MYSYS shrimp as well, so they get a good mix of foods every week.
