  Housing
Tanks can be either glass or rigid plastic. Xenopus should have 2-5 gallons of non chlorinated and chloramine free water per adult. Allow them to have places to avoid light if so desired. Frogs do like to bask if allowed to do so. Keep water level so frogs cannot escape or use a soft top enclosure with good ventilation.


  Feeding
Feeding ideally should be done daily. Animals should be fed as much as can be consumed in about 15 minutes. Xenopus should be give a nutritional high quality balanced diet such as Xenopus express' exclusive floating and sinking frog foods. Tanks should be cleaned after feeding to remove uneaten food. This can be done using a siphon or even a turkey baster.


  Temperature
Xenopus Laevis should be housed at 20-23 degrees C (68-75 degrees F).
Xenopus Tropicalis should be housed at 23-28 degrees C (75 -80 degrees F).
If the water temperature is sub optimal... frogs will not eat and their metabolism and immune systems will be depressed. Xenopi cannot raise their body temperature by producing metabolic heat. They must rely on external heat sources. Tanks in cool rooms should provide a heating source. Low wattage rare earth phosphorous bulbs are useful and prevent burns. Submersible heaters can be wrapped in plastic mesh to protect frogs from burns. Xenopi are sensitive to temperature changes within the room as well as the temperature changes of water.





  Water Quality
If using tap water, it is necessary to let the tap water sit for at least 24 hours to allow dissolved gases and some chlorine to dissipate before the water is used. This also allows time for the water to adjust to the current room temperature to reduce stress to frogs. A de-chlorinizer / water conditioner should also be added to water. If de-ionized water is used...be sure to verify a correct pH range (6.5-8.5). Water that is over saturated with dissolved gases can cause gas bubble disease (bubbles under the skin and in the webbing of frogs).

Recommended Water Hardness

A GH of greater than about 200 ppm works fine for increasing oocyte firmness and normal embryo development rates. 200 ppm (mg/liter of CaCO3) and alkalinity > 50 ppm (mg/L of CaCO3).

  Lighting
12 hours a day of indirect UV lighting is recommended. Photo periods can be achieved with an automatic timer. Black lights and rare earth phosphorous bulbs are useful when wanting to view animals at night time without disturbing them.


  Enrichment
Providing a pvc half pipe in the tank can be enriching and comforting to your frogs.


  Housekeeping
Cleanliness is the key to healthy and productive animals. Cleaning should be done a couple of hours after feeding. When changing the water or handling animals you should wear gloves. Traces of soaps, hand lotions, colognes and ointments which remain on the hands can be harmful to Xenopus. Frogs have permeable skin and are very sensitive to toxic substances.


  New Arrivals
Our frogs are shipped in sealed eps foam containers with damp sponge to prevent drying out and to cushion any bumps during transit. Our shipping containers provide appropriate temperature, space and oxygen. Frogs should not be left in warm areas like loading docks. They should be promptly unpacked.

We recommended if possible, that new arrivals should be housed in separate holding tanks and should have separate nets for quarantine animals. Frequent hand washing procedures and glove changes between tanks of different shipments and between individual frogs.
