Odd thing about Isolation Tank

When you find that your hybrid is dying, what you should do is to place that hybrid into a isolation tank and wait. Its health should slowly rise instead of decreasing in Isolation Tank.
It seemed that isolation tank is better place for the fish to live than regular tank.

Fish still can get sick and lose health in the isolation tank.

I'm not sure if this trick can work on Fish Tycoon on PC.

I'll have to try that on my DS. I have a game on pause right now that is trying hard to reach the 3rd environment level, and I have a fresh batch of babies that I don't want to lose.

Yeah I noticed that on my friends Nintendo DS version but it didn`t work on my PC version.
