Hey,
I like that: "I don't have ick YET...". lol
They are scavangers and will find stuff to eat without any direct feeding. ie. detris on the bottom. HTH
Take care,

At dinner time my 3 come out and run around the bottom until they find a piece of food the fish missed then they go back to their rocks and sit there esting it. They will eat live worms, mysis shrimp, brine shrimp, formula 1 & 2 pieces. As said they forage for food all the time and doubt they would ever starve.
