My tank just got annihilated. One week ago, I had three chromis, one neon goby, one algae blenny, two clowns, and a six line wrasse in a 40 gallon tank. Today, I have two clowns and a six line wrasse. I am not terribly upset, since the three remaining are my favorite fish, but I have no idea what happened. I found a new one gone every day. I actually never found the final chromis. I have never seen aggression from those three fish. The water parameters are all safe, salinity was a bit high at but I have corrected this. I'm not watching 24/7, so I imagine those fish, or my coral banded shrimp, could be bossy when I'm not around…it's just a sad day. I have a thread about moving my fish and potentially rehoming some from the 40g to a 29g high which has suddenly been made much easier. Still…damn.
