" Mandarinfish only spawn in the evening and exhibit very unique mating behavior. If a pair of them are healthy enough, they will begin spawning occasionally just after lights out. The male and the female approach each other and begin to "dance" in a spiral up the water column. They release sperm and egg as they rise. The spawn are planktonic for some time, but will grow to a couple mm in length in a couple days. If there are other kinds of fish in the tank, the spawn should be isolated. Sablans också. Tror att mina andra fiskar kommer att sluka det mesta
