I have a 1 yr old WTF, still relatively petite, who pulled a toddler move on me. The bottom layer of the tank is filled rounded gravel pebbles, and, in parts where there is no moss or rock slabs, the gravel is exposed at the surface without cover. well, my one little guy took a running leap at a cricket and gulped down a large, but round (no jagged points) stone with it before i could pry it out of his mouth. my whites have swallowed small stones before (because i find it in their poo) but never one this big. i have watched for the stone to "reemerge", but it has been two days and no luck. he doesn't seem too distressed but he also doesn't seem to be moving very much either. Is there anything to do, HELP!
