They have not been big eaters in years, the males were way smaller and more sleek in body shape, recently this one had taken to freaking out at lights out and bouncing off the tank sides which i think has hastened it's demise and accounts for the red marks.It's certainly an impressive fish but there could well be a clue to its demise there. That fish looks like a football, it's all out of proportion to me. I know that tinfoils are a very greedy fish, I have them. Couple that with their immense speed and they can clean up food before any other fish has ate it's first mouthful. That fish looks like it's eaten itself to death!
Yeah that's an exceptionally good innings for a tinfoil. Are you after replacing it? I'm only up the road in Lancashire. I have two tinfoils i'd let go free to a good home. Mine are about 11-12". They're about 4 years old. It would probably only take an hour and a half to get to me.They have not been big eaters in years, the males were way smaller and more sleek in body shape, recently this one had taken to freaking out at lights out and bouncing off the tank sides which i think has hastened it's demise and accounts for the red marks.
Also is 13 and a half years not a good lifespan for a tinfoil then?
