I never get tired of this video...even though I no longer have these pikes it still one of my fav. Its a bluff/fight between my dom. male Crenicichla sp. 'xingu II' and my Crenicichla lenticulata. It was more of a standoff and nothing really ever became of it. However, it gets the point across how pikes won't always like other pikes. If you see these signs, and it continues to escalate, its time to make some changes. I think you will have to click on it to view it...haha.
. Then you should see why so many peeps want them!! Rare and pretty!
