Food Fed to Parents and How Often* Aquarium coop magic floaty food every 1-2 days in addition to the live bugs and other critters that eventually populated the tub.
Breeding triggers: the great outdoors. Parents were put in tub in May 2026.
I had these in an aquarium for 2-3 years and no fry were ever observed. I thought they were a lost cause or too old to breed. It was a pleasant surprise to find some fry in the tub!
