I just bought two african dwarfs a few days ago and bought freeze dried bloodworms for them. I tried feeding them today but they couldn't seem to find the worms, since the worms were just floating at the top. They seem to know the worms are there, as they come out of hiding and look upwards, but they don't actually eat any of it. Even when they go up for air, they're nowhere near the worms.
Should I get something else that sinks, or is there a possible other reason they're not eating? I'm really worried they'll starve!
Thanks!
