Will the red tailed shark hurt my African Clawed Frogs

I have an African clawed frog. I went to the pet store to get another clawed frog but they didn't have any. Instead my boyfriend decided to want to get a fish to put in with my frog saying that the tank looked too empty with just a tiny frog. The pet store lady said that a red tail shark goes great with a clawed frog so we bought it. So far they seem to get along great but I want to make sure my frog is safe with the red tailed shark. I don't want anything to happen to my frog. So the question is will the red tailed shark hurt my frog? Any help on this subject would be greatly appreciated.

 

How big is the tank? Aggression is always reduced with space, and sharks get huge, they are generally aggressive although I
Can't picture how they'd bother your clawed frog as they get huge also, especially the females, they should be fine as long as given enough space

 

The ACF will eventuality kill the shark. They try to eat anything that moves. It maybe too small now but the ACF will grow faster than the red tail, and will injure and kill it at some point. They are not mean but they will eat until there is nothing left to eat.

 

10 gallon is too small for a red tail shark, your frog may eat it too, it's best to house them with their own species

 

Red tail sharks grow over a foot in length (I'm not sure the exact length) so a ten gallon is way too small for them. An ACF is a very aggressive species and should be housed by itself, as it will eat anything it can fit in its mouth.
