Hi, I just got my 2 adfs yesterday and they are pretty small. They didn't have any sinking pellet food for them so they gave me freeze dried blood worms. I tried just putting the food in and leaving it there, but I don't think it sank and no one got it. Then I tried hand feeding it by holding the food right infront of them but they don't do anything ;( Should I go to the store and get sinking food instead?
It's likely that they're feeling a bit stressed from the move. They'll be fine without eating for a day or two - keep the tank lights out and give them time to adjust - they'll likely happily take their feed after they start settling in.
As far as food is concerned, from my understanding (and there is some debate here) the freeze dried foods aren't terribly good for them, as they can expand in their tummies, causing bloat. Bloodworms are good, but it's BEST to feed a variety of foods - if you're going with frozen foods, use the wet-frozen type. These are found easily, even the big chain stores will have a freezer, though you may have to ask after it. The pellets are good, just make sure you get the right type - and for the record MY ADF refuses to eat the pellets at all! If that's what they were being fed in the shop, then yours might react differently to them. I feed a mixture of bloodworms, brine, bits of tilapia, whiteworm. . . there's a long list of possibilities! With the frozen foods, be sure to defrost them before feeding - they will sink to the bottom when thawed.
I'm sure someone else will chime in here soon with more advice for you, but for now I hope this helped! Good luck - and keep us posted on your new babies!
