Sorry if this has already been posted before, but i now have level 2 environment, the aeration system, and also the temperature regulator, but i still have some of the baby fish dying.

Do i need to improve still further on the environment?

The most fragile hybrids will not remain healthy in a Level 2 Fish Environment. Once you get to a Level 3 Fish Environment, you will be able to breed any combination of fishies without having to worry about whether or not they will survive.

ok, thanks....have only just started playing, so will have to do some saving
