:Has there been color changes? I heard that frogs that are stress their color will change. Anyway, you maybe feeding it too much. Sorry to worry you. Sometimes they do that when you feed them a lot like every other day. Wait another week and if they eat give them the crickets the next 3 or 4 days. Feeding them twice a week is enough. Mine will do that when I fed it every other day so I switch to twice a week and their eating fine.
Maybe I'm wrong can you please describe the toads appearances and how they are behaving. And how often do you change their water. You should everyday.
