I got him/her last night along with a pleco. I was told that the silvertip like to hang out at the bottom mostly. This one is particularly obssesed with the top and stays in one spot, he reminds me of the pleco who remains stuck on the side of the tank, the silvertip is staying up against the side. Is that normal? Anyone else have silvertips? What sort of behavior do they show? I am considering getting some mates for it, but I want to get to know it before hand. Also, how can you tell if its a male or female.
