I think it depends on the temperature of your tank, I'm sure there is a reason if not that because I eye them up many times and say its a pity I can't have them.
Fingers crossed someone will prove me wrong then we can both get them lol

I think it depends on what type you wish to have. Once your LFS has some just google it. They can tolerate temps from 22-28C. Most need a fine substrate . They should not be housed with fish that nip and need fine sunstrate. look at this web page http://www.liveaquaria.com/product/prod_display.cfm?c=1075+1642&pcatid=1642
They would not be my cup of tea so to speak, but would be interesting to know if you go ahead as I have never kept any. cheers jk :thumbup:
