I had a pleco named Spike for like 6yrs, he was a good size guy prob 12in+. He lived with my turtles and was a diligent cleaner. One yr, we had a heat wave and no a/c. I was desperately putting ice and cold water in. Temp said it was fine. So started watching some tv, heard lots of splashing and commotion in the tank. Looked over and my turtles were eating his stiff dead body! Poor guy cooked to death. I also had a giant(like 6in) goldfish named Niblet, (he grew up w/ Spike, and survived that heatwave), one day he was swimming slowly, and acting weird. Next day he looked like he was covered in thick white mucus. My turtle snuck up on him and bit off his head. He wriggled around for like 20sec. then my other turtle came and finished him off. Poor guy

I had another pleco for like 3 yrs, he came down to CA from WA in our car, did great. Was filling up my tank for the 2nd time w/ my new water system, and I didn't know god damn thing takes 50yrs to reach its temp, and as it raises, levels off periodically. It ended up wayyyyy to hot and cooked the pleco. I now check the temp every few min, just to make sure... the goldfish were on the brink of death(floating), but they bounced back after i put them in cool water. One of my current goldfish got sucked onto my water circulator, didn't see him for awhile, i noticed, turned off the circulator, and he had a huge indentation from being sucked on. I thought he was dead, but he lived and still has a huge misshapen, scaleless indention on his tummy. My current pleco Shadow, is growing quickly(4-5in) and sleeps w/ my tiger oscar in their cave, and is the only resident that the oscar will allow in her cave. It's pretty cute. I'm making sure to be careful w/ this one!
