*************************** This one caught me completely off guard. The night before, there had been no particular sign that any nymph was about to emerge, so I went to bed without paying it much attention. But this morning, I saw an exuvia perched atop one of the chopsticks standing in the tank.
It appears to be the same species as before.
Today, I set up the aquarium that arrived from Charm and transferred the medaka into it.
With 10 medaka in a 45-cm tank, there’s plenty of space.
The medaka are swimming around happily. Soon, I plan to move the troublesome upside-down ryukin goldfish here as well. By the way, that particular ryukin was floating again today, so it’s currently having a cocoa bath.
