Why is my Oscar fish lying on it's side and has red sores on it?

Question

She has been doing this for a while.

Answer 1

Because she is very sick. Most likely a bacterial infection if it has large open sores. I would suggest you treat the tank with Maracyn or Maracyn 2 for at least 2 weeks to clear the infection. Odds are good she may also get a fungus infection in the wounds, so you might want to be ready to treat for that a well. Feel free to email me if I can help further.

Answer 2

Laying on its side is the #1 sign of resiratory illness. Where are the red sores? Gills? Head? Back? Stomach? This could help diagnose the problem a bit better. Short term advice? Do a 50% water change and test for nitrates which should be no higher than 25 ppm. Remove the carbon (if you use it) from your filter so it doesn't interfere with the medication. Treat with Metronidazole and Nitrofuranance. Live worms should be offered when she feels like eating. Make sure to do ammonia checks as the medication will affect your biological filtration.

Good luck :) I hope she pulls through.

could be some countless issues. regularly Mickey provides relatively reliable experienced solutions so i do no longer choose to bypass against that. you certainly do no injury holding reliable water high quality, yet you may have many distinctive pathogens strike and have super water. So weight loss plan comes into play here. i'm curious to appreciate what you're feeding it earlier in simple terms going to water high quality basically. to boot, your tank length and if there are the different tank acquaintances can component into this. Have the suitable water for the fish, yet shop that Oscar say at 10 inches in a 20 gallon tank, considering that severe filtration can shop the water in simple terms superb, you will nonetheless have well-being subject concerns. Oscars are known for doing issues such as you listed, each so often this is from being unwell, each so often in simple terms being "bored" with this is enviroment to boot. this is complicated to make that assessment with out having any seen recommendations to technique too. confident run your tests on your water, and your nitrates is often as severe as 40 ppm and do little to no injury in any respect to a fish, yet you ought to additionally record your tank length, tank acquaintances if any, the load loss plan and positioned up some photos. Very infrequently does a fish ever die off of starvation actual. If we evaluate the organic habitat of those fish, nutrition materials can substitute into scarce many situations and not something around for weeks. Fish do no longer use nutrition interior the same way people do, so the shortcoming of urge for nutrition, isn't some thing to be deeply distressed approximately at this factor. an thought of the tank length and your filtration delivers some easy on the priority back.

Oscars often do this by lying on its side, meaning he's unhappy. Even a healthy oscar will show this. Do a PH test on the water and do a partial water change every week with aquarium salt.
