Hi! Yes- I still have Minion. And he's still in a tank WITHOUT gravel. He doesn't have very discriminating taste when it comes to things that fit in his mouth! I am glad that you're switching your beasties out of the pebbles. Poor Minion was suffering quite a bit when he ate the rocks and I'd hate for another frog to go through it! I was lucky that he survived. Would love to see some pictures of your frogs!
