What's going on with my Cardinals?
So I have setup my 25 gallon planed and everyone (except my cardinals) seem to be happy. It's been about 1.5-2 weeks now since I put them in and the tank was already cycled. Water parameters seem to be good but the cardinals seem
stressed. Here's a video...
They seem to constantly swim on that side of the tank. Almost like they are trying to escape? They've been doing this since day one and they never seem to be very mellow.
Tank is 25 gallons. 4 guppies, 9 Cardinals, 3 Otos and 4 Threadfin Rainbows.
GH is 120
pH is 7.0
Thanks for any help!
