So yesterday I was cleaning my tank, and decided that my pleco looked like he was breaking out in some sort of infection. (I now realize he was just losing color from the temperature bump.) So I put him in a 20 gallon long tank just incase, because I don't want any of my other fish getting an infection or any illness for that matter. Well I wake up this morning from a dream where I feel like my pleco could have jumped out of the tank. I reassure myself when I wake up that, A. I would of heard the noise and woken up, and B. that he wouldn't push off the top to get out, and if he did it would be loud.....I then thought about how tired I was last night, and I knew I would have slept right through it. I walk over to the tank, and he's not in there =[
(I bet you saw that coming) I begin searching my room...
5 minutes later I find him. He is right by my bed....Hard as a rock, dry as a bone. No gill movement, nothing. I decide to take a shot, and hope for the best. I put him in a tank with alot of waterflow, and a few airstones. After about another 5 minutes, I see his gill move the slightest bit!
I was sooo pumped when I saw this! I kept wiggling him around, and I poured some "Slime-coat" mixture into the tank. 15 minutes later, he suddenly comes back 100% and fly's out of my hand, and down the length of the tank! I then had to run down to my cross country practice, and I made it just on time. After the 7 mile run, I ran back home, and he's alive and "kickin"! 
Lesson learned, weigh down the lid, don't expect a fish not to be strong enough...And even if the fish is seemingly dead...Try to revive them! I hope you all have a great day!
