One of my brothers purchased two very tiny African Clawed Frogs (Xenopus Laevis) for my kids as a surprise gift. They came in little cups as if they were from a carnival. He purchased a nice 5 gallon set up and told me to change the water only when necessary... as if I needed another living thing to care for. I have a smorgasbord of food available for them from freeze dried bloodworms to actual aquatic frog food and Wardley's flake fish food. We have had them for 3 weeks so far and I have only changed the water once a week. I used plain old bottled spring water. Does any one have any pearls of wisdom to share with me so that Squirt and whatever the other one's name is don't go to frog heaven before their time? Thank you, Laura
