Just curious, do the hermit crabs in my tank need larger shells to move into at some point? I have seen them change shells but with existing shells in the tank. I guess they are older shells from larger crabs or snails that have died.
I am new to salt and never had anything like this in freshwater.
Also, at some point is it beneficial to add new cleanup crews? I seems like there are less in there from when they were first added.
