Debating the pros and cons of getting rid of my hermit crabs, tank is an 18.5 gallon low nutrient system quite full of coral. I have plenty of coral in the sand bed and I'll be getting a big acan colony of 10 or more heads this Sunday I just find that the hermit crabs are annoying and knock over a lot of my corals and cause them to close up often my question is do you think it's safe to get rid of them? I was wondering if anyone has chosen to get rid of their if their tank has been up for a while (mines been up for over a year and a half and it's very stable) also I have a fireshrimp that cleans the tank up a lot
