Update hes back up and swimming.
I am amazed hes ok because from the top of the tank to the floor it was a 6 foot drop the tank is a 150 tall. Not to mention he was bloody and barely moving when i tired to nurse him back to health. Hes a little bit scared when i come to the side of the tank to look at him. I think he did get spooked by the little juvie Alligator gar, i just added him to the tank because i was redoing the 125 gallon. I dont plan on keeping the alligator gar i was actually trying to sell the fish a week ago and no one bid on him. I do have plans for upgrading the tanks soon but the alligator gar will keep getting bigger and it was a mistake on my part for excepting the fish without any consideration for how big he will get. More the less my friend bought the fish and handed it to me so i dont really consider it me buying it but i should have told him to take the little guy back and find something that would not out grow my two tanks.
IPejelajarto i did infact add salt because i noticed the slime coat was pretty much gone when i found him on the rug. And i left the normal two air stones i always have running in the tank, He has stopped breathing heavy and is almost 100% normal. He does his normal breathing of air when he goes to the top of the tank. Only thing im worried about is that he still went to the top of the tank and did a mini jump which i never seen him do. Honestly i never thought for a moment that he would jump. But i thought wrong, My 125 gallon is covered very well so nothing can jump out at all.
I am very happy he is alive like i said i would have been very mad if i lost my oldest and favorite fish on account of me not putting the lid back over the top of my tank.
I thank everyone for the concern about my fish And thank you for the useful advice.
