We got 3 koi angelfish recently. When I feed them they would fairly
leap out of the water for the flakes. However now one of them is
sometimes found hiding under the filter. When it's not hiding and I
drop the flakes in, it will come up to half an inch of the flakes,
then just look at it. Tried dried blood worms, it took just a nibble.
Tried thawed frozen worms, it swallowed one, spat it out, and repeated
that a couple of times, finally rejecting it. What could be the
problem and what can I try next? thanks...

You said you "recently got" these Angels.
Angelfish are notorious about going on a *hunger strike* when newer.
Sometimes they'll do this right away, and some may wait and then stop
eating.
They usually come around and start eating within a week.
When you talk about the Angel "hiding behind the filter", does that
mean it's just hanging around, kind of like swimming in place behind a
tube for the filter, or is it wedging it's self under something?
There's a huge difference between the 2, so please be specific.
