Do any of your guys blue spotteds 'pace the glass'? Like a tang in a small tank does, sort of rub their nose in a a semi-half circle repeatedly? I searched some vids on youtube and noticed another one doing it. It seems like his tank might be too small, a 55gal QT? He's only got a couple more days before the 4 week holding period is up. Just want to make sure everything is okay.
