I get home late from work (10-11 range) so my office where the tanks are is all-ready dark. Over the last few days when I come in and turn on the lights the rasboras are staying mostly still but twitching (it looks like trying to stay in one place in the current) while the ADF and Betta are usually swimming around. Tonight I came back and the rasboras were all near the ground doing the twitching thing. They were not on the gravel, just right near it doing the same twitching thing. Is this normal for a fish at night? Also the rasboras seem paler than they were when I first got them... is this normal?
Just wanting to make sure I don't need to worry. Thanks
