Erpetoichthys calabaricus (Rope or Reed Fish) are notorious escape artists so it isn't a surprise that yours took an extra-tank excursion. I would venture to say that the most common cause of death in captive Rope Fish is dessication on the floor.
These are truly fascinating fish but , like their Polypterus cousins, they'll often take advantage of any opening you leave for them. Experienced Polypterid keepers know to make sure that their tanks are as secure as humanly possible and even then they occasionally experience losses. Just a couple of night ago I woke up in the middle of the night to a loud crash as my 16" Polypterus endlicheri endlicheri finally managed to push the heavily-weighted aquarium cover free and apparently decided to go for a little stroll. Fortunately I was able to get him right back into the tank and no damage seems to have been done by his drop from the tank to the carpeted floor.
I am certainly sorry to hear that your E. calabaricus didn't make it but don't let that put you off keeping this fish in the future. Chalk it up as a lesson learned and make sure that your tank is as escape-proof as you can make it before putting another Rope Fish in it.
