I have had my dwarf frogs for about 2 weeks.I am very happy with them.Then one of the frogs was on the top of the water verystill and moved occasionally.I put him in my hand whill still in the water to see if he moved.He didnt and hasnt for twenty-four hours.The store told me the frog will be on the bottom of the tank when it dies (like me previouse one) unless it has a certain desise. I checked it for the dises and i didnt find anything.Do you think its time for him to get flushed or is it just playing dead? Please tell me what you think.Thanks.
