Thank you all very much for your replys
I will try feeding these too
Is there any prepared food of suitable size for their mouth that sinks instantly?I ask because flakes,Hikari micro pelets and crisps(forgot to say that i have been feeding them Tera Pro Crisps too recently) sink slowly and because all the surface of this aquarium is covered with Vallisneria leaves,they get stuck on them and very few make it under the ''Vallisneria barrier''

So currently i am mostly relaying on the Tetra prima for them to feed as the other dont make it in sufficient quantitys...
Thank you very much in advance
