HorseShoe Crabs

[justlooking]

So I bought 2 very small ones. About an 1-2 inches long. They are kind of neat but basically burrow and walk around under the substrate. I have CC substrate. They are in a long established 46bow tank. Anyone have any experience with these? I have heard mixed things with some people saying they aren't going to grow too big in the tank and others saying they could grow pretty big. I have mostly small fish in the tank:

Yasha Shrimp goby
pistol shrimp
cleaner shrimp
couple other small shrimp
barnacle blennies (3)
jawfish- chinstrap
clown goby
firefish
watchman goby
bunch of hermit crabs and 2 emerald crabs.
geometric hawk
2 red headed gobies


that's it in the tank. Only recent addition was the jawfish- everything else has been in the tank for quite awhile.

These animals are peaceful, and large. We used to use 12 inch specimens in the lab. Probably your biggest problem will be their knocking things, like rocks, down.
