TY is the boss of all my aros. When it was only 14" it killed my former 22" jardini that I used to have when I place all my aros in my 700g tank last year. Also killed my one and only lei aro. That setup was a biggest failure. I know it's normal for aros to fight and flare up or chase each other especially when introduced so I thought I just let them be. Boy as I was wrong. TY at 14" was doing a killing spree in one night. Shreaded the fins and barbels of my other larger asian aros too that why I sold all my bigger high end aros. I don't like aros with no barbels.Was your Green chasing the RTG or TY? TY right?
