I got 3 threadfin rainbow fish yesterday! 2 females and a male. At first, they were just hovering behind a rock. But now they are swimming around the whole tank. The male is already showing his fins off to the ladies and they all seem to like each other. I do have a few concerns though.
1. They wont eat. I am giving them flake food, and making sure it is really small since they have small throats, but they wont eat. Is this normal for new fish?
2. Sometimes it seems like they are stuck in the currents of my filter (125 bio wheel). Should I be worried about them getting sucked up or are they really not stuck?
Thanks! I am so excited! (And how old do they look?)
