In the beginning of the game, the common eggs were fine, now they dont survive, the one I haave kept from the beginning are fine, the black sharks, and a couple more of the black sharks have survived, some I toss at the age of 8 because the health is going down, I have had a couple betas since they beginning that are fine, and there offspring grow up healthy, the leaffish are fine, the leafish in the common eggs die, betas in the common eggs die, more used to survive but now they just die, and the spontanus fish I have had since the beginning are fine, but those again in the common eggs die, (one might survive every once in a while, and if I breed a beta and a leaffish, the babies die, I haven't been able to breed anything, with something different. It's getting sad not to be able to see new breeds, I Have 4 games going, and in one of them I used the mystery chemical, and a couple fish changed, and then there health deteriorated after. Thank you.
