Sooo cute!!! I know what u mean, they can be such pigs hehe

I have the same problem with my telescopic goldie...it can't seem to see food to zoom towards it as fast as the others. However I learnt how to hand feed it...basically put food very near its mouth and it'll snatch it from me. Slowly it trusts me enough to do this daily. However the pig ones are also learning the trick, but in which case, I ignore them hehe

I also throw sinking pellets towards the hungrier fish quickly when the faster ones are not looking (find out a way to distract them elsewhere), this works for me
