I have been trying to breed mine for nearly 2 years now without any sucess or anything that looks like sucess! What were your water params? did you do aything to trigger them? I have the same caves from smithrc, however, my male prefers the cave he has dug out under some bog wood. What size group do you have? I am looking to add to my grou, but I havent seen any for sale for a while.
Cheers
Ian
