mexican dwarf crayfish

[icecube]

Hey everyone,
I need help in setting up a tank for the mexican dwarf crayfish.
I was able to get hold of 4 of these guys, i dont know how to sex them(can anyone help me on this?). Currently put them in a 20g tank with lots of hiding place, driftwood and pvc pipes, should i be adding any plants to the tank, no plants added at the moment.I am currently feeding them on algae wafers and live tubifex, but they dont seem to like any of these, anything else that i should feed them that they like. Any tips and advices would be greatly appreciated

Have mailed you the details, did not put it up here as it is a link to an external website.

Coming to food, mine were taking Hikari Algae Wafers .... maybe they need to get adjusted still
