I used to have a puffer named 'Ziggy the Miracle Puffer' because he survived so much! He was one of my first brackish fish, and the tank was a one-day set-up with live sand.

Through the years, that tank crashed numerous times and he enjoyed tankmates like a moray eel (big green wild kind), toadfish, scats, monos, archers, lots of sailfin mollies, burrfish, gobies, skilletfish, and numerous others. Once he even suffered a massive hemmorage in which some of his insides came outside! He was once so sick he was on the filter uptake, and I surely thought that was the end of him. Several times I would put my hand in the tank and feel a buzz - something (heater, light, etc) would give the water a little charge. He even lived through a bout of brackish-tolerant oodenium (ich), parasitic polychates, and there were times when he was only thing in the tank!

However, he did eventually sucuumb to old age not too long ago. We will all miss him terribly and hope no other fish has to suffer through what he did!
