Hello guys,
Tank is 4 1/2 ft by 2 ft j have a mbu puffer 6" with 1 parrot fish 5 discuss. Isn't bothered by any other fish, he normally eats 1-2 muscles daily but hasn't eaten since Wednesday. So 1 week now. 0 ammonia And 0 nitrite. Nitrate =40 -50 (tap water is high where I live). I have 2 big air stones and a juwel filter. All he seems to be doing is sitting at the top of the tank which he normally doesn't do. He's also breathing very heavily and looks abit fat asif he is bloated. Please can someone give me some advice.
I done a 40% change Sunday and another 10% Tuesday. After the water change I also treated for bacterial infection.
The fish is also flicking sometimes.
Please help
