Thanks to both of you
They are schooling and foraging fine, especially since we release the pinch of food underwater now so it sinks for them. The food seems a little big for their tiny mouths so it gets spit out some but everything from last night was gone this morning.
I gave them more this morning since I wasn't sure if they'd eaten much the last few days but. They're seeming to do fine. There's one I call loner fish who's off by himself sometimes but he's not acting weird.
Do they move so quickly, especially when on the side of the tank, it looks like they're shaking a tiny bit? I think that's normal.
They rest on the sand a lot sometimes but I think that's normal. Some of the fins look a little flatter but that's when they're resting and not swimming.
They seem fine...
I didn't actually buy anything yet since I haven't had a chance yet. Decisions decisions.
