In a 75g wide with heavy filtration. I'm not sure whether he will be ok here for life but i am always willing to upgrade (excelent excuse to tell the missus of why i need a bigger tank).Mudfrog;2552657; said:What size tank is yours in? There aggression usually goes through the roof once they hit 12" or so, sounds like your right on mark.
His aggro started to really kick in at 9" for me but has increased ever since.
