i dont think they do but i would wait for a better answer
The isolation tank in fish tycoon is that little box that, when you put your fish in it, will show its age, what type of fish, health, and if its fed.
It helps fish age faster than others.
When you hold the fish it will say what kind its status(which will say pregnant) and age
It should make the fish in the same tank age faster, and maybe keep them healthy.

Your fish will live forever as long as you take care of them and they don't get sick/they get treated rapidly when sick. However, the age number will cap out at about 9999.The oldest fish I own is a 235-ageunit old Speckled Beta, and she is still at full health.
At the age of nine months
depends on what fish you have.
You Can Fish At Any Age
the same way they fish now!
