I saved up my hard earned goldbulb coins to try out that unknown chemical (from the day I bought this game I've been dying to try that). It made the Magical Fish of Mutations! Course.. I have a level one tank and he died

Any way to keep those suckers alive while you try and get enough coinage for a new environment? Soo... a new environment = 3 days-ish for me.
Oh yeah.. I know I know.. shoulda worked on environment before playing with the chemicals but the suspense was killing me!
