I’ll look again, but I think one of the 4.5 inch earth eaters I put in with the bichir, and silver dollars is missing, that is the only tank I have, that is covered, as the bichirs have been known to be aerial acrobats.. the acrylic tank has a top, and all the openings are covered… lots of good plastic plants, and live Java fern in there, but if it’s really missing, the only explanation, is a 14 inch bichir, ate a 4.5 inch earth eater… if that’s what happened, must have been a battle… the earth eaters have a history of being brawlers, so maybe the 2nd one is hiding in a corner somewhere, so I’ll have to look again for sure
