My clown has gone missing from my tank! I've looked everywhere and no signs of him. I did install a AquaC remora skimmer with a surface skimmer box. I thought maybe he got sucked in (I don't see how but I looked anyway) and nothing. My other clown is in QT and the only other fish in the main tank is a red lip blenny. I was told by LFS that they are alage eaters. Could the blenny have eaten my clown?
