African clawed frogs resources/conflicting information

Question
Hi Jennifer,

I've had a pair of male African clawed frogs (albino) for a year. They live in a 10 gallon tank with a glass heater (temp avg. 70-75F), natural rocks, built-in light (rarely turned on, as there is plenty of natural light in the room), a plastic plant and a live, petstore-purchased plant. I've been doing some research and have found a lot of conflicting information about their health.

Do you have a reliable site (or sites) regarding husbandry? I've primarily used allaboutfrogs.com, but I'm interested in something with more references due to the conflicting information I keep seeing.

Questions about conflicting information you may have thoughts on:

1. Distilled vs. "Natural spring" (purchased) water? Internet sites and petstore employees disagree on this one.

2. Treating the water: most sources say to treat the water, but I've just read another article that says frogs should never be put in treated water (http://www.geocities.com/ptimlin/xenopus.html).

3. Feeding: I feed a mix of tropical fish flakes, reptile sticks (broken into small pieces), and aquatic frog food (although I've never seen them keep the reptile sticks down). Some sites insist they can't survive without bloodworms or brine shrimp.

4. Filters: Some sites, including the one referenced above, indicate that the vibrations and/or water movement from filters stress the frogs. There are anecdotal accounts of the frogs "liking" the movement of the water.

I would love to read your thoughts (or references) on any of these. :) Thanks!

Answer
Dear Danielle,
thank you for your question and thanks for the good rating :)
1./2.: Distilled water doesn't contain any minerals, but both the frogs and especially the live plant would normally take some of the minerals they need from the water. It's possible to re-mineralize the water, but it's easier and probably cheaper just to use normal bottled water or treat tap water to remove chlorine/chloramine from it. Treated water is not a problem for the frogs.
3.: I'm not too sure about the reptile sticks, usually those contain nothing of value (neither for reptiles nor for any other animals), most of these products are produced cheap and have next to no nutritional value. It is a good idea to offer the frogs some live food so that they can hunt. The diet of any captive animal should be as varied as possible to keep them healthy and to keep them "entertained" - offering live food or different food at each feeding is a good method of behavioral enrichment.
4. Since African Clawed frogs live in stagnant waters, a filter can be a problem and constant water movement would disturb them. They also use  their lateral line to sense water movement to hunt for prey.

There are some filters that are very quiet and keep water disturbance to the minimum, those can be used. This website has some more information (on food as well):

This website has husbandry tips and excellent links:

I hope I was of some help to you
