OK, if you follow these setps, the fish settings dialog will "allow" you to designate 31 fish as starfish....except, you still really only get 1, and the other 30 are randomized:
1. Click All Random
2. Click Total Fish up to 30
3. Click on Starfish
4. Click Number In Tank up to 31
Now, the number on the starfist picture stays at 1, but the number in the left-hand column shows 31.
