I've been feeding my silver a diet of Hikari Bio Gold and crayfish for 12 years and he is nice and plump and has spectacular color. Was thinking about using Hikari Massivore Pellets....anyone have any luck with these?
Or you place them carefully on the top, and maybe the surface tension keeps them up. I admit, not exactly an answer lol, I just notice it when i throw them in now and again, they don't sink.
