Hujeta gar refusing to eat

[poutpotato]

So I got 3 new hujeta gars about 4 months ago, everything was ok until a few days ago when they refuse to eat. They chase the minnows I give them then stop when they're close to it. And I don't know if this is their normal behavior or something but they kinda stay together when eating and sleeping basically everything they do they stay together.

They are a schooling fish that occupy the top zone. They’re doing what they do naturally. I’d try some flakes, tubifex and floating foods. Should eventually take it.
