The regular underwater frogs that you are thinking of have to be African clawed frogs since any other aquatic frogs are far less common.

There's really no frog called a "regular underwater frog", so what exactly do you consider a regular underwater frog? The most commonly seen fully aquatic frogs in pet stores are African clawed frogs, Xenopus laevis, and African dwarf frogs or dwarf clawed frogs, genus Hymenochirus. Rice-paddy frogs ("floating spotted frogs" to the pet industry), Occidozyga lima, are also seen from time to time and are heavily aquatic.

The reason I ask, is at our store we have what are simply labeled as "sm underwater frogs" and "albino underwater frogs" upon closer inspection, I realized that they are indeed african water frogs. We use a filter in the tank, and It's interesting to learn that they don't like filters. I also want to know about how big do they get, because cutomers are always asking, and I never know the exact answer. Also, how many can you keep in a simple 10 gallon tank? thanks for everyone's help. I love to learn new information so that I can pass it on.

From what information ive gathered, What youve got at your store is almost certainly African Clawed Frogs, because their close cousin, the African Dwarf Frog doesnt usually come in the Albino variety...and they also dont usually get as big. If taken care of properly, African Clawed Frogs can usually get to the size of a fist. This is all purley thru research tho, i dont have any first hand knowledge for you as the two I have are only frogletts, (about a max of 2 inches from butt to snout so far), and i didnt know these guys even existed before "adopting" them about a month ago...

African dwarf frogs/ dwarf clawed frogs don't get very big, less than two inches. They also don't have "claws" on their rear toes like the clawed frogs do. I'd estimate an adult clawed frog at about 4-5 inches long and fat. They're quite unsuitable for keeping with fish. Aside from the fact that filters do them harm, they also eat fish. At 4-5 inches, most aquarium fish make a tasty snack. I would only keep one or two clawed frogs in a 10 gallon.

I have had mine with a filter for several years and they have had no problem, but I don't use a bio-wheel (tends to produce a lot more vibration because of the dual filtration system), I use a whisper, and mine have had no problem, a friend of mine did research on lateral lines (my friends and I are fish geeks aka Marine Biology Majors) if you raise the frogs from a young age in an environment with filtration they do not exhibit signs of stress, if you put them in a new environment when they get older that has filtration or unusual vibration or motion in the water they will stress badly. It is the same for fish and other aquatic amphibians, they require conditioning. I have never changed the type of filter on my frogs for this reason.

Males are MUCH smaller than females, and tend to make a fair amount of noise at night. If you don't feed regularly, or you are late on a feeding it is not inconceivable that the female will attempt to eat the male when they are full grown, be careful about tank mates, I have seen tanks in which the frogs have attacked large cichlids as well as plucked the eyes off of snails. They are voracious predators.

All and all they are easily the most dynamic and fun animal you can keep in an aquarium.

Thanks for everyone's information. Do they need any type of heat or photoperiod? Should people provide them with a heater in the water, if so what should the temperature be?

The temperature of the room should be adequate, if you are concerned about your house being too cold, a good rule of thumb is, what is comfortable for you is comfortable for them. If you are the type that keeps your house pretty cool then you can try putting a small tank heater in the tank. I don't use anything fancy lighting wise, they are in line with my iguana set-up so they get 12 hours a day of light, however I am not sure how necessary that is as they are shade loving, and tend to live in murky water
