So today a friend of mine that is a full-time clamer in the bay gave me a sea cucumber,, It’s not very big maybe 2 inches by about an inch thick I would say the size of my thumb more or less I think it’s pretty cool looking and I’m going to start it off in my 10 gallon tank and if it does well and after I do some research to find out if I could put it in with my Seahorse and coral I will move it,,if it’s not compatible it will stay where it is
