Thanks guys.
I don't want to rub it in, but yesterday was my birthday and today I received more presents. Found two more male L397 on fresh eggs (both caving males in photo below are on eggs as of today). Four L397 spawns in 2 weeks. Dang that makes me happy. When everything else does nothing, or worse, dies, it's really affirming to have good news.
But to be fair, it's all the fish. August is also peak L397 spawning season in my tanks. My first spawn was two years ago, wigglers discovered around Aug 12th. Last summer was another rush of spawns.
This summer was relatively quiet with just a few spawns in June and July. Now they're hitting it, and they're hitting it hard!
Cheers, Eric
