Best animal to breed for credits/money in Franchise?

[Hitopopamus]

I've had pretty good success at farming credits in Franchise by starting a new bare-bone zoo with a couple habitats breeding Ostriches in mass and releasing them into the wild as they mature. Netted me about 2k credits in an hour.
Wondering if anyone knows of other animals that breed quickly that one could make a quick profit off?

Gold ribbon Bengal Tiger (those with high in genetics) sells for like 600-1000 if you release them.

Apparently red pandas are easy to reproduce. They accept larger groups and grow up within 2 years (or less?), they sell with gold ribbon for 350CC (150 with no ribbon at all)

Get your hands as fast as possible on a lion male and two lioness, they reproduce like crazy and gold ribbon lions can get you 1100CC/lion (the also grow up within 3 years)

If your willing to sell them in the trade center, Red Ruffed Lemurs are my favorite. If you can get a few of them going, the females sell for something like 1000 cc each, and they're dirt cheap to keep.

If i told you that then they won't be worth a lot.
