I've had a red carpet haddoni for 4.5 months now. It's doing great, eating, sticky, mouth is closed. I've been feeding frozen fresh shrimp because I've read instances where a bad silverside made for early demise. When feeding the shrimp, I thaw and de-shell. My questions are, is it necessary to take the shell off the shrimp? I know it's not done that way in the wild. Are there beneficial vitamins within the shell? Thoughts are greatly appreciated.
