Ya looks like a silver tip. Quick story.
I had bought two crazy looking swordtail from my LFS, for $3.99 so i went online and looked up what it was and they were the rare and expensive "blood red sail fins". So I had them for about two weeks and went back to the fish store and saw another cool looking catfish about 5 inches long. Turned out to be a silver tip. Woke up the next morning and there was red fins sticking out of his mouth!!! He ate BOTH of them, and he died because of it. Now I NEVER buy a fish unless I know what it is.
