they certainly are mean to each other marina. i hope to introduce an anemone later this week. back when you were selling chrysogasters, i think you had them displayed in individual little plastic breeder boxes....right? what company makes those?
as for the very dead and very red fry, no other problems. this nest didnt hatch the night it was supposed to, so that was annoying. and i suspect that could have been the case for the problems after they hatched. my gut feeling was something chemical got them. no idea where it would come from unless it leached from the aquarium itself, but that was just my initial gut feeling. as for the ammonia, i do not test for it. but watch the seachem tester, and the water. they get a water change a day, with a few spritzings of prime throughout the day as well.
