    @Turok - Pics please. By dissapearing do you mean closed or empty socket?

    @Turok - Did they definitely have 2 eyes when you bought them or were they fry? Could be a birth defect. Bad breeding, raising etc...

    I've never kept a ghost knife - but I know they're nocturnal feeders. I suspect he/she is the culprit here... I googled a little, and it has been documented that they can learn to chomp their tankmates eyes out while they're "sleeping".

    I'm sure the more experienced members will have an opinion or options. I looked around the net and the only thing I could see was the reference to fish bought like that so not sure. Sorry. :(

    Ghostknife is the culprit here @Turok I experienced the same problem, and caught him redhanded. They are actually very aggressive fish

    @Turok,

    My guess is it's the knife fish.

    I had a banded knife and it used to just bite the heads off other fish, and leave the rest of the body.

    So far, my BGK is hasn't harmed any of my other fish, but apparently, I need to watvh out when it gets a bit bigger.

    Definitely your BGK, had the same problem with mine. They are in fact very predatory fish and them being nocturnal makes it worse because your danios and tetras are "sitting ducks".. Apparently once they start doing this they don't stop, like a dog jumping a fence.

    If you feed your bgk correctly (minced fish, minced prawns, bloodworm etc), you might break the tendancy to attack other fish.

    But as @Double-D says, once a knife starts this, it is difficult to get it to stop.

    Well I can also confirm it's your black ghost knife.
    I also have the same problem but only 1/20 cory cats
    Eye has been eaten. I know for a fact it was done
    As there were still blood by the socket. All my other Cory
    Have Thier eyes intact.
    What I do, before I go to bed is that I put 2 shrimp pellets 2 algae wafers
    In front of his/her cave. When the lights go off. All Cory would
    Come close but the bgk will chase them off and nibble the pellets.
    As said, not more lost in eyes.
