We have a wonderful comunity tank with a school of Red Tail Razboras, a school of Halfbeaks, four HillStream Loaches, and two Kolie Loaches. This weekend a friend decided that our aquarium needed something more "elegant" and suprized us with two Black Anglefish. I was concerned but he was experienced and insisted that they were a "comnunity" fish. We added them to the tank and they floated in as is they were home. I kept a close eye to make sure there were no nips or bites on any of the other fish. Tonight I came home from work and all fish were accounted for (minus the Kolie's who I typicaly don't see until after the lights kick off anyway). We fed the fish and it was the typical mad dash for foot. About an hour later, I looked in the aquarium and the smaller angle fish was gone. I asked my wife and she said she had seen both Angels twenty minutes before. We did a search of the aquarium and could not fiind any evidence of the other angle fish. Is it possible for an angle fish to swallow another one roughly the same size?
