I have 4 thin-striped hermit crabs in a Fluval 13.5 nano build. I collected them from a bay in florida which led to me setting up a saltwater tank in the first place. they are all a pretty good size, using shells roughly 1"-1.5". You can see pictures of the tank below and there are also shells in there for them. With the rock work (which they climb all over), I'm worried that I may not have enough room for all of them.
I've also added 5 fish now, so do I have too many animals in there? so far my levels seem fine. But I guess the main concern is there just isn't a ton of room for the crabs.
Also, I want to add corals at some point, so I'm worried all these crabs may either walk all over them or eat them.
They do a great job of keeping the sand clean however, so that's a plus. But any guidance would be appreciated.
thanks,
