This is bit of a lengthy story. I am a novice hobbyist, that has had many tanks along my years. Anyways i have a cichlid that jumped out of the tank "unknown" for how long. Can only confirm a least 2 hrs. Anyways i was ready to pick up a beautiful dead fish. But to my surprise it's gills were moving, i thought to myself this cant be. But as i looked again yup his gills moved. He was partially stiff, but not bad. I put it back in the tank and sunk to the bottom for a little while, i decided to see if it could move, and sure thing like a bat out of....yeah.. Then back to laying on the bottom and slowly over the next 3 to 4 hours it was swimming then laying....Got up this morning and wife said he was still alive. (High Five). I came home from work today and he isnt laying down much but on one side of it (i assume exposed side) has a build up some sort of white layer. I can add pics if needed. I added melafix to the tank about an hour ago as of this post. Is there any advice or knowledge of this happening with anyone... I would appreciate any feedback. Thanks for listening.
