Green Tiger Barb Can't Eat

[Mati2s]

Hello everybody, my Green Tiger Barb can't eat, he tries to, but after he eats something (flakes, bloodworms, granuls) after 0,1-1 sec. he spits it out, today he tried to eat some granuls, but after few unseccesfull tries he lost interest, he looks very thin ;( Looks like he will die... Is there any why I can help him? Thank you for answers. Tank: 120l (~30 gallon) with 8 tiger barbs, real plants, 30% water change every week

if it is small the food may be too big for it. if you crumble up some flake and put it in he may be able to eat that.

cheers
