Mt tank is not fifty years old. Lets not get crazy. It is only 44 years old. When and If it reaches fifty, I may take it down as I will also be up there in years and don't know if we will be moving or just inviting in Supermodels to assist with daily stuff like morning bunjee jumping for breakfast. Someone has to help me tie the cord to my feet so my head doesn't hit the tile floor.
Thank you guys for your vote, but I think there are so many very nice tanks on here and very accomplished aquarists.
