Yeah I know! I've been feeding them separately once a week with tongs to make sure they don't get too hungry. Maybe eventually I'll be able to gain their trust and lure them into a trap with my tongs or something. For now, they're very skittish. I've had the two of them for a long time since they were little, and they've grown A LOT since then. They came in a reef cleaner crew package that I bought from E-Tropicals. I figured that if they were included in a cleaner package they'd be okay in my tank, right? Maybe not! They do an excellent job on the algae and detritis though, I've had much better results with them than with emerald crabs. But they are much more quick than emerald crabs (which would be no problem for me to catch if I had to).
