The eggs are all stuck together in a ball. Interesting to note that I harvested the egg mass via siphon and it broke apart, but it all re-congealed together in the egg tumbler!

In a cave, in the back corner of the tank, barely noticeable but I thought maybe the male was hanging out back there lately and maybe he'd dug out enough that I could see the cave...sure enough, there the eggs were, kind out in the open almost (there's a

Other Details:

The male in this pair was a "replacement" and initially they did not get along...they were two random "adult" Ps. flavivertex thrown together. They are almost the same size, although the male is far more blue than the female....I think that's due to diet or care or different genetic lines, not so much to do with sex. Arguably, this pairing is likely the result of the bidirectional hermaphrodism suggested by Wittenrich in his 2007 book, which I also proved with Ps. cyanotaenia a couple years back.
