1mm should be fine for 2.5" syns. Try presoaking them using tank water, for 30mins or so, to help with soften the hard texture
Unfortunately I got my fish from Aquabid... I emailed him asking what he fed him at first but at the same time at asking i was telling him about how the fish came with ich and that he shouldnt wrap the heat pack in so much newspaper... i feel like i may have embarrased him/her thinking that i wanted a refund... i quickly cured the ich problem and they are sorta eating(they spit out the flakes asap)... but regardless i cant get in touch with the original seller. as for the pellets... my ebjds dont eat them either :/Best to find out what the previous owner or store fed the fish with. Fish that are used to eat one type of fish will not readily switch to eat another food, so there is some adjustment period. Most fish will accept NLS pellets. If 1 mm are still too big, use a roller to ground it down to powder.
