I feed every three days live feeds, black mosquito larvae, and other frozen food.
Daphnia and Tubifex.
The boys get living water fleas, and frozen bosminids (twice a day).
I've caught two males is not ideal. In addition, the two boys are certainly 1.5er come up, so I will remodel the pool in a few weeks.
The Schneckenbubas known as moles. But I think, I have the "kinds" caught which is darker in color and there is living in the lake, where less free of sand and stones are more.
But the basin is transformed something many stones come away and the ground is increased.
On the "Terrace" also is a deep layer of sand.
