Raise those Little Critters!

So you’ve successfully bred hermit crabs, so what should you feed them?

It’s suggested that you add zooplankton on their food since it contributes to the larvae’s nutrition and health. And once they are seven days old, you can begin feeding the young ones a pinch of powdered spirulina or brine shrimp daily. 

And when they reach 14-day old, you can place itty bitty conical shells in their habitat! 

When they start to wander around, make sure to provide the younglings with fine-grained sand that will be connected to your salt-water tank. Once they reach the 40-day old, you can include them with the other hermit crabs.
