Hermit Crab Shell Size

[reddogf5]

What is the largest size shell that should be available for hermits? Mine are the common blue legged variety for sale everywhere, and I want to make sure there are enough shells of the maximum size for them. Any ideas as to rough size, opening dimension, or anything else? Haven't been able to find a good answer to this anywhere.

Just a little bigger than their shell. They can get pretty big but that takes a lot of time, no need at all to keep shells for their late size.

I have a couple bigger/older blue leg hermits that have upgraded to shells with roughly 1/2 inch diameter openings. Shell length, about 1.5 inch. From what I've read, this is probably the max size they would need.

Also, they seem to grow faster if they have bigger shells. I ran out of the larger shells and the hermits stuck with the smaller shells seem to have stopped or slowed growing. This is just an observation and may not be entirely true.

This was what mine used.

Thanks, 1.5" with a 1/2" opening is bigger than they have, I am going to find some larger shells to keep them from fighting or attacking snails.

Would These work? My blue/red leg and Hawaiian hermits need larger shells
