Hi guys, I've had my red bellied Pacu for 9 years now. I have him in a 200 gallon tank with a 1 year old pacu, a few guppies, 2 large goldfish, and 2 plecos. They have a Rena XP3 filter, along with power heads, and air pumps, and heaters. I think I need mroe aeration though.
So let me explain the situation. My tank is at my parents restaurant, and I currently go to college. I'm back for the summer, but was gone the past week, so a waitress was feeding the fish. Long story short she overfed... a lot.
When I returned, the tank was cloudy (green), all the fish were near the top for oxygen, and there was a ton of uneaten food on the bottom of the tank, and the water smelt horrible. I did a 85% water change (without a siphon), and added melafix.
The problem: My pacu's lower jaw seems to be "swollen," or the jutting out. Makes them look bulldogish. It seemed to get slightly better with the water change, but it has me scared. What do I do?
Thanks for any help... and I know long posts are annoying, but I wanted to explain the situation.
