any update? poor froggy. i have no advice for you. i got my group of FBTs from a local petsmart. i put them into an empty tank with no substrate, and on the first month I saw about seven little rocks appear in the bottom of this tank. The first few rocks came in a few days. The last rock came out three weeks later!!!! I was amazed that it took them weeks to **** out the substrate that they had eaten at the pet store. fortunately, I saw no health issues other than they had some rocks in them that took a while to come out even though they were feeding and pooping daily.

i figure maybe one of your toads got too many rocks. no idea what to do in that case. sorry.
