Congratulations on your success. I've kept a pair for 9 years myself now. They were wild caught and required a significant regimen of treatment to rid them of all the nasties they had in their sysyem. True all things are possible, but as a general rule i think it's a bad idea for the majority of keeper's to try and replicate what you have done. Just too many chances for something to sneak through. But then again I may be overly paranoid. Have you had any breeding success with them so far?
