More species in one tank

[gr81]

Is it possible to have more species in one tank?
I have:
C. Denticulata sinensis RS.
C. Serrata - Red Crystal
C. Babaulty green
Will they crossbreed or can they be together?
Will it have efect to thery reproduce? (will they harder breed with other species in tank?)
Thanx.

I'm not sure about the C. Babaulty green but to my knowledge many people have C. Denticulata sinensis RS. and C. Serrata - Red Crystal together with no problems and no crossbreeding.

Hope that helps for now, till the experts come in here... :)
