I'll have to try that.
Right now, he is guarding a bubble nest (largest and thickest I have ever seen even in pictures) at the back of the tank. So it's hard to lure him out for anything.
I have a half giant HMPK female that has a superb cadual. Full 180 spread with very sharp edges. She and my HM girls are the only ones I can get to really flare. One of the HM girls has a slightly long anal. The other two are pretty well balanced.
Sitting here observing them, my newest female has a nice cadual as well. Hard to get a read on the rest of her as she faces me as soon as she realizes I'm near the tank. I have a true blue female that has a lovely cadual as well. She's more submissive.
