I have kept amanos in numbers for years. They get berried all the time but I do not try to breed and then raise them. I hate salt water itself. I have not gone swimming in the ocean in close to 50 years. I will not even hatch BBS because of the mess salt makes water makes.
However, a fish friend was into trying to hatch out and raise amano babies. She would come here and I would let her take the berried ones home. She managed to succeed in raising them to some extent and she would bring me back some babies when she came for more berried females and to return the ones she had taken.
My water is on the soft side and neutral pH. I also have assassin snails. I need to add a bit of crushed coral to tanks with these things in them. I have a 75 gal. jungle tank with both shrimp and snails and I have to add a bit of SeaChem Equilibrium as well because of the plant/shrimp/snail load.
I used to buy imported amanos in 50 or 100 shrimp lots.
