Why aren't my blue-tails breeding?

[RandallRock]

I've had a group of 6 C. Cyanurus I got from jennewt about two years ago. I've followed every letter of every article I've read regarding their breeding however they still have yet to show eggs. What could I be doing wrong? I'm pretty sure there are 3 males and 3 females.

Thanks all

My first reply was going to be "are they all female"? I'm finding that more than half of mine turn out female. But.. you say you have males, and if they have the blue tails, then that's not the problem.

What temperatures do you have (winter/summer)? Are they plump? Do they have some plants to lay eggs on?

I have one group of cyanurus that are unbelievably efficient at eating their own eggs. I know I've seen the females laying, but I never find any eggs or larvae. This is another possibility.
