As the title says I’m looking into crabs and I wanted to use a old 45 I have. And I was just wondering what would be better for an inexperienced person to start with fully aquatic or semi aquatic? I understand that crabs won’t be visible all the time or hardly ever and I’m okay with that because the plants would be enough to look at the crabs are a bonus.

I also am willing to buy everything brand new including an enclosure since mine opens from the top as I used to house a scorpion in it.
