Can't get GBTA to eat

[rydr119]

I have had this GBTA for about a month now and I can't get it to eat anything. It looks ok but I have tried squid cubes, krill, Formula 1 Cubes, nothing works. I make sure the food is defrosted before I try feeding it and I gently place it over the mouth and it closes up and then just lets it go. Do I need to be worried? Should I try a different approach?
Thanks Gina

try silversides. BTAs often have a food preference, you just have to find out what it is. It mat not be crustaceans, so try fish
