You can raise them on berries not just toxin

Feed the babies Mejoberries easier to raise then using bio toxin

Breeding tip baby turtles eat berries and biotoxin

I saw one on the Center as well. Should mark it as on The Center.

When raising baby Archelons they have to be fed Bio-Toxin or they'll starve, use a Basilosaurus to farm some before hatching.

You can ride them underwater without a scuba!

Archelon is on the center, ive seen it near the redwoods forest beach

I have found that stocking up on biotoxin in advance is recommended for raising. Even mejoberry troughs are melted when raising multiple turtles. Biotoxin, in my experience, lasts quite a bit longer for sating their hunger.

Also: finding the “Slow Metabolism” trait and putting it on the babies will help save your troughs as well!

Lots spawn around the south tropical island on the center

The best way to raise them is with the algae produced by the adults!
