Yesterday I noticed my Jardini arowana was swimming funny, like struggling to keep level vertically and throughout the day it progressed to him not being able to stay at the surface because he would sink if stopped swimming. When he eventually made it to the top he could stay up there well enough but his dropped varying 25-60 degrees depending on how much he was struggling to stay at the surface, and occasionally he would swim spastically in corkscrews and loops in one place for several seconds. I read online that it could be that (if you have a lot of air stones creating large bubbles) he swallowed air and its messing up his swim badder. Treatment for this said i could put him in a plastic bag and pump air into it. So i put him in a plastic bag and put an air hose plugged into my air pump for my tank and put a rubber band around it thus filling the bag with air. From what the treatment said it seemed i was supposed to keep the fish in the bag for a day and keep the air pumping into the bag. I did this over night and when I woke up it had only progressed and he was hardly moving. I put hhim back into the tank and he cant really swim at all. He flaps around but just corkscrews around on the bottom. Is he too far gone or can I stay still save him? Im praying for the best because I really like this fish and have only had him a couple weeks or so. He was perfectly healthy when I got him and didnt start acting weird until after I introduced the new airstones. He is only 4 inches long. I shouldnt have gotten the air stones.. Please help and reply quickly, I am in a terrible hurry as he is just sitting on the bottom!
