Hey there! My parents recently went to the beach and brought home a hermit crab for my 5 year old- without asking.
I have basic knowledge on hermit crabs.
Luckily I have a 10 gallon tank lying around the house for this fella to go in for now. I’ll upgrade to a bigger size soon.
I know about substrate, water, temperature, and humidity needs.
I guess biggest questions are

1. Best diet recommendations? There’s so many options it’s a little overwhelming.
2. Enrichment ideas?
3. Does it need a friend?
