To vary my juvenile FRCS diet I give them a (single) tropical fish flake every other day, in addition to their main Hikari shrimp cuisine diet. They seem to like the flakes, but I was wondering what else I can do to vary their diet. I have only just started giving them one or two of the Hikari pellets a day since I am not sure how many to give them – there are four shrimp in total. Pic is from when I first got them, they are now about three times that size.
