i recently lost track of a yoyo loach in my 55. after cleaning up my room a little bit today i found a beef- jerky style yoyo loach under the wood stand. if my room were cleaner i may have found him in time to save him.
sorry to hear about your loss, loach. it must be that time of year because i had the same thing happen with one of my albino tiger barbs. i found him on the floor all dried up. poor guy/girl.
