I would recommend joining the Yahoo! Groups on this (Dwarf African Frogs). I have two. It's recommended that two adults per ten gallon. They are farsighted, so finding food is a problem for them, but you can feed them with a turkey baster. They like raw Tilapia, tuna, and catfish steaks, frozen and live brine shrimp, mysis shrimp, krill, Daphnia and such things. They do not eat flake, whatever you may hear. Blood worms not high enough in nutrients to be their staple diet, and they should only receive them about twice a week. They prefer a PH between 7.5-7.8, but will do fine in 6.0-8.5. Their preferred temperature is between 74-76 degrees, but they will be fine up to about 82(unsure about this part).
Right now a virus called the chytrid fungus is affecting these frogs. Therefore, it is usually recommended to quarantine them for 2 months at around 75 degrees. You can look up the signs of the virus online. There are several theoretical treatments; the yahoo group is testing a heat treatment which can also be done as a preventative. I would not use any of the chemical treatments as preventatives. The chytrid is almost always fatal, and if you see DAFs in with African Clawed Frogs (beware! some pet stores try to sell you these instead. You don't have to worry about it if you're in CA, but if not, these guys grow to 4 inches and will eat your fish), they will probably be infected and die.
There is a good sticky article on this website, also.
Those tiny turtles ARE illegal to sell as they will grow into foot long red-eared sliders, generally. However, some places get around the law by selling them "for educational purposes only"(yeah, right). I don't think there is any turtle available in the pet trade that could live its life in a ten gallon tank. Our red-eared slider outgrew a 30 in 4-6 months, maybe less, can't remember at the moment. Probably less.
