Rainbow crabs

[bev911]

Hi ..... am new to the site and could do with a bit of help...we are interested in getting a couple of Rainbow crabs but the ones we've seen are being kept at Hollybush garden Centre in a tank full of water with fish and everything I've read leads me to believe they are semi-aquatic crabs!!, been told of another place in Bromsgrove with Rainbows but they have just told me their crabs are Tri-coloured or Red Clawed Crabs, looking at photos on Google they look the same as the Rainbows we've seen ..... very confused now, have set up the tank 1/3 water with bog wood n rocks for them to climb on and have been running it for a week with treated water, would it be safe to put anything in there now???? helppppppppppppppppp
