Hi Christy,
It's funny, but mine do the same. Even if I just want to look at them, they swim to the top thinking its eating time again!

Hi
That's what fish do . They quickly learn where the food comes from. lol You can feed 2-3 times a day in small amounts if you like but don't overfeed. You'll note that they lose interest almost as quickly as they feed.
As long as they're eating it all it's not too much. gary

Think of them as trained teenage boys!

they always think they are hungry , its your job to not overfeed them, as tempting as it is.

Yes, they all act like they haven't been fed in over a week! They all do that! Mine would feel my step vibrations and come to the glass even when I don't stop to look at them.

a resounding YES!!!

Okay that's good because I thought that I was kind of like abusing my fish because they spend 90% of the time when they're awake at the top waiting for food! I feel bad.
