Hi new to the forums, I recently added two sexy shrimp to my 10 gallon reef tank, I acclimated them for 20 minutes. When they were added in they swam to the bottom and hid in my rock work. Its been three days and I haven't seen one, what are the chances they died in my rock work and how badly would this pollute the tank since im not going remove my rocks ? My tank is 1 year old, it as 2 ocellaris clowns and 1 Court Jester goby. As for other inverts a Turbo, Nassarius, Cerith and a Nerite. I have never had anything die in my tank yet so this a first for me and not to sure If I should just continue weekly water change + just daily check ammonia just in case, just checked my ammonia and its at 0.
