My alpha male is already guarding more eggs! This is right off the back of a spawn in the last month. I'm not sure where the other babies have gone. I'm not sure if they're in the cave, or maybe they've wandered off to hide in the bogwood. I'm not sure. But dad is definitely guarding a big pile of eggs. Must be at least 10 there.
Congratulations! That does seem to be the way of it with them. Once they start they spawn like mad until something makes them stop. Good luck with all the wee ones!
