I have 5 gallon tank with 2 African Dwarf frogs. I had the tank cycled and left my oldest adult dd to feed while I was out of town.I came back today and she had changed all the water and cleaned the tank!!!! She did add prime but they are gaping fro air and trying to get out, I have a 2.5 gallon hospital tank but I a afraid I will shock them to death. Getting test kit ad testing the ph now.
