    I had 3 blue chromis, around 2-3cm. I've mysteriously lost two. Nothing in the sump, outside the tank.

    I have a pair of hermits in my tank, as well as a boxer shrimp who is pretty big and cleaned shrimp. Is there any chance that they have caught the chromis when it's sleeping and devoured them. The went missing a few days apart.

    My nitrates are zero in my tank, so no sign of anything dying.

    Chromis are known to fight with each other if they not happy. It is a possibility that the one didnt accept the other two.

    The one that's left is the smallest guy, almost half the size of the other two. All from the same tank at the lfs. I didn't find any body's, so can't understand, they were there before lights went off and this morning one missing.

    Do you have any cats? or other pets.

    I had one that disappeared and couldn't find it until I cleaned my cats basket and found his bones. The cat stole the fish chromis before i got to the tank in the morning.

    If it died, the boxer shrimp would be able to devour the shrimp overnight. With some bristle worms they would be able to pull in the corpse under the rocks, out of sight.

    If it died and you did not find it, then your clean up crew did what they were supposed to do.

    Had you checked the skimmer inlet? If skimmer is performing as it should. I found a lost blennie that went exploring the overflow in the skimmer pump.

    Thanks Riaan, I will check just to be sure.

    My worry is that the boxer is killing the sleeping fish, is that possible? Straight he that he went for the biggest guys first.

    Quite normal with Chromis, there seems to be some kind of 'sweet spot' whereby they will live happily together, until you can figure out what that is, it is quite normal for them to disappear one by one, lol.

    This seems to be a common issue, I had 5 in the first 2 weeks one jumped out the tank and 2 went missing, the 2 that are left seem very happy now for over 2months, planing on adding 4 more,
    What you guys think should I or should I not add more.

    I freaking gave up. If I lose a fish, I lose interest in trying to keep it.
    That's just me.

    lol.. a bit late to party, here is 50 cents anyways.

    I think your hermit could have caught him, I have seen my red legs try get my chromis's late night when they sleeping on the rock work. As you know the red legs are darf hermits so I can only image what a proper sized hermit can do. Anyways this is just my experience and the norm.

    Also in experience I find larger groups tend to do better, between 5-9 is good number if your tank can handle it. In he past when I get 3 of them one always becomes a target and then a few months later the second one dies for reason.

    Btw... this is all anecdotal and just my experience.
