Hello, everyone!
Lately, one of my boys, Smaugstark (I couldn't decide between the names, and eventually they just stuck together!), has been listless. He's been facing one corner for ten minutes barely moving...then another...then another...sometimes, it's not a corner, but all he really does is listlessly float in place! He used to be aggressive, and follow my finger, etc... All of his conditions are fine, and the other boy in his divided tank (who he used to enjoy flaring at!) is absolutely fine and normal. Could this be a personality change, or could he be depressed? He has plenty to do! Lots of hiding places, live plants, and his favorite silk plant! Has anyone else experienced big personality changes like this?
