Mopani is a very dense wood from Africa, it just sinks and very heavy. Popular here in the States for Aquariums and Repites. But I have no doubts now that it was buffering the tank water to 6.6 – 6.7 pH
So the driftwood is out of the tank. All 6 babies were out eating Moina this morning! I’m very pleased not to have any loss.
The ones I suspect are males show the beginnings of a brilliant blue stripe on the borders of the dorsal, anal and caudal fins. No other colors except the 2 dark bars that are the body length.
They love the brine shrimp so I will start trying some soaked decapsulated shrimp eggs mixed in with the hatchlings.
