when i first got my ngt he would only eat blood worms. they told me at the pet store that he was eating krill, but i doubt that cause after a week of just a few blood worms a day he still wouln't even look at krill or shrimp. so basically l bought enough blood worms that he could have a good meal for about 3 days and during that time i traped some craw fish that he gobbled up. i stopped the bloodworms and moved to earth worms wich he took fairly readily a week no food and he started to kill those earth worms and go crazy on anybody that went near them. well after a month of that i decided it was time to sart the shrimp step. well needless to say he is not completely dumb after a 8.5 weeks of straving he ate his first bit of shrimp two days ago. it was a piece one of my ITs had in his mouth and the ngt stole it. yester day he had a small piece that fell to the bottom of the tank. and today he is now attacking the shrimp when i put them in. now the only problem is that my two bigger dats will grow much faster that the smaller ones cause they eat like crazy and are not afraid to hit the top of the water before the food even drops in.
