Problem in feeding

[FishyFishFish7]

So I just recently recieved my puffer in the mail and it seems I have the wrong order, instead of being a Carinotetraodon lorteti, she turned out to be a Carinotetraodon salivator. At first I was angered in not getting what I ordered and being the first time I ordered a fish online but after doing some research I realized my rare puffer was a lucky mistake. The problem I am having with her is that she will not eat dead or frozen food. Tried bloods worms and frozen squid, clams, and shrimp...but nothing. Then a suprise one of the guppies that I had used to help cycle my tank survived and was quite large now and she attacked and killed the poor sucker. She tried nibbling at him with no luck so I broke the guppie into two parts (very gross) but after she wanted nothing to do with it. I am getting her live food today but I really don't want a nothing tank to breed food for her...is there any way I can turn her diet to frozen food fast?

There's an article in our library on how to train picky eaters (under the Learn tab).

Best method though is to fast her for a few days, then offer her something good. The problem is, some of the best foods for these fish is live, snails mainly but crickets, etc too.

Ok thanks, so throughout the day I left her alone to get hungry enough and for her meal tonight I soaked frozen squid in warm water and fed that and she gobbled it up! Thanks for the advice
