Schedule Feed once a day. If there is food visible, remove it with the

spoon to avoid water contamination.

Reduce amount of food fed if food visible when time to feed again.

Check water level, add new water every other week by removing 2 cold cupfuls of water and replacing it with 2 fresh cupfuls.

Ideal temperature is between 77 and 86 degrees.

If water becomes cloudy or algae occurs, empty tank water by placing frogs and plant in holding pail of conditioned water while cleaning habitat. Use paper towel to remove algae, and rebuild habitat.

Feeding Observation1. What happened when you put food in the tank?

2. Did all the frogs respond to the food? What happened when you moved the food with the spoon?

3. How much food did the frogs eat?

4. Did the frogs eat from the surface or bottom of the habitat?

**You should observe the feeding carefully and discuss the above questions each time.**
