I feed my nem by placing a Silverside over its oral cavity and gently letting the nem take it. I then keep my hand or the net, kinda over the Nem to keep my femal clarki back till the fish is 1/2 swallowed or more. It takes about 5 min. I dont think she would take the silverside, but she always crashes into the nem hard when my hands been in the tank, and I dont want her to mess him up eating.
