Nervous Guppies???

I'm glad they're doing better today. Yes, some fish do like to play in bubbles or filter flow. No, 1 degree is not enough to matter at all.

They may be happy to see you...or maybe all the extra swimming room has made them hungrier, lol.

Normal behavior for a new home. They are testing the boundaries and should be fine by now I suspect.
