Hi,
Bought a pair of red hermit crabs on Saturday morning and put them in my FOWLR tank and they were happily eating the algae in the tank but that night nticed that 1 of them came out of the shell and was crawling around totally exposed without the shell. Unfortunately, did not last long and was soon eaten up by the fishes in the tank...foxface and wrasse. The same thing happened to the other one yesterday.
Question:
can anyone tell me why they left the shell? The shells seem big enough for them.
and
how to prevent this from happening?
I want to get more hermit crabs so any advice is helpful.
Thanks
