10 years and more 
He'res my severum, before I rehomed him. Wish I didn't have to but he was anti-social. One of the most interactive fish I had, if I put my fingers to the glass he would come up and start attacking and displaying to them, getting irridecent greens and blues on his body. Photo definately doesn't do justice.
White marks are on glass, not severum.
