I take it its a tropical tank?
Either way - you should only do a 10 - 15% water change once a fortnight. Changing the water any more than that will make the fish ill and stressed. Last time hubby changed the water he did a 30% change as it had been a long time and it killed 95% of the fish we had. We've now got a massive tank with 2 tiny tetras in it
The water will be cloudy for a day or two after you change it as all the residue will be floating around until it settles down. You want this residue at the bottom of the tank as it stabilises the water. Think about fish in the ocean/rivers - they don't have tap water with all the chemicals, its a long term stablised environment built from rock, sand, plants, pee, poop etc all degraded at the bottom of the ocean/river floor. Fish are very sensitive to water conditions (ph, ammonia, nitrates, nitrites etc etc) so you have to be careful when changing water be it with water changes or additives.
I'd not touch the tank now except for putting in swim bladder treatment. Cover it with a blanket so its dark inside and only lift off the blanket for a few hours a day. That will help the algae etc build up again and will calm "ish" so he isn't so stressed. In a few days he hopefully will be okay. I'd just tell Kaden that "ish" is a bit poorly and wants to swim in the dark for a few days and he's got to be extra calm to help "ish" get better.
In my experience if the tanks been changed that much with a sick fish, its not likely to survive. I really hope "ish" does though for Kaden!
