Have had an O. briareus for about 6 weeks that has been doing great. When he came home from the LFS his diet was pretty much silversides. I have been giving him both shrimp and little neck clams from the seafood dept at the grocery store. He def seems to prefer this to the silversides. In fact he wants nothing to do with the silversides anymore. He gets all his food off the end of a "feeding stick". For the past couple of days when I go to feed him, he does not reach for the food. However, if I kinda "slide" it under him he accepts it and eats. Is this common or normal? Is this something I should be worrying about? Any of his other habits seem to have remained unchanged, and all water readings have remained the same.
