Dwarf Frogs And Tank Mates

[jeepgirl]

Hello I wanted to know if anyone knew how long it takes for dwarf frogs to get use to there tankmates and quit hidding? I have two dwarf frogs and ever since I put in 6 zebra danios they have been hidding alot more and haven't been eatting like they were. They are all in a 55 gallon and the ammonia is at zero and all the other water ph ect.. is good. So the guy at Petsmart told me that the frogs are just really shy and sometimes it takes them a while to quit hidding and that they could go up to two weeks without eatting. So I wanted to know what ever one else had to say if you had any of the same situations??? They have been hidding and not eatting for about 5 days now, they could be eatting underneath their cave were I put there food at when I am not watching but all the times I watch I never see them, and before I added the danios they both ate like little pigs... Thanks for any advice.
