Crosshatch trigger and cleaner shrimp. Or Neon Gobies. ??

Good to hear, thanks. It seems like the scales are slightly tipped in favour of trying although seems there is still some hit and miss. Someone eats snails in the cube tank although I can't tell if it's the eel or the trigger. Either are about as plausible.

Yeah I've had her since December 2009. Great fish, great personality. She lets me scratch her head. Although she's also nipped fingertips once or twice too. When I was reaching in a few weeks ago to pick up a clam to transfer over to the new tank, my other hand had just the fingertips poking through the surface and this must have looked like ..... food or something. Didn't draw blood or anything but surprised the heck out of me as I didn't even realize my other hand had breached the surface at all.
