mmm i heard they are some what hardy. just feed them a varied diet, with lettuce, wafers, etc., and keep the parameters (ph, kh, amonia, etc)and temp stable and the should do fine. they need driftwood to munch on for nutrients and they need hiding spots.
yes they are spiffy, pretty snazy, eh? i would get some if i had the $$$.
you can do a google search for them or look 'em up in the MFT freshwater profiles section.
