I set the tank up purposely and designed it as the best possible system to keep Mandarins.
I knew that pods proliferate in piles of rock, therfore the way the rocks are stacked, there are plenty of places the Mandarins cannot get to for the pods to breed.
I set the culture up before buying 1 of them and was prepared to buy food initially if needed.
I also read everything I possibly could on getting Mandarins to feed on frozen food. Tonight the male has taken food with his head out of the cave and directly from the end of the syringe. That is a first!!
Most of all, I was prepared to do everything I possibly could to get them to thrive.
My LFS is a good one, she has had a female in the display tank now for 4-5 months. But mine are twice as fat as that one.
I was lucky with the initial stock, but keeping them has been down to me. If I can get them established in the tank, they should live for years.
