My Jag

[afinity]

I have a Jag that is around 6''-7'' long. He is pretty agressive, so when I bought an Albino Oscar the other day he's been swimming up and down the back of the tank near the water inlet and air bubbler, pretty much nonstop. So im wondering if he is just stressed or mabey this is fish language to the Oscar. Any ideas would be appreciated.Oh I also fed him his first feeder fish.

Hmm well fish do this for differant reasons. Sometimes a simple change of some sort will trigger this, such as a new addition or deco rearanging.Other times they do it because of poor water conditions.I think you may have a mix of both since the new oscar and the feeder fish may have caused a spike in your tanks bio system. Either way he should settle down pretty quick,as I doubt he's scared of an oscar at his size.
