Reefing newb
Ok I have been on this site before and all my water is fine but something is killing everything in my tank. I am wondering If it could be a emerald crab or any type of crab we already had one hitch a ride to out house in the crevices of our live rock and my mom thinks there is another one. We also know that there are certain types of bristle worms and in the past we have removed a few bristle worms in the past that are a very very pale punk almost skin color but today I notice a long bristle worm with a dark purple back if you have any other things that could be killing them please let me know ASAP I only have 2 fish please tell me :(
