Adult Oscar (5 years old) hasn't eaten in 5 days, and is exhibiting odd behavior. Rapid, Rhythmic breathing and gill movement, and an overall spaced out look, where he is just swimming in place and not responding to any stimuli. The breathing isn't heavy, but it is faster than normal, and very rhythmic. There is a very occasional "cough", and then back to the rhythm. This isn't the typical Oscar sulking. All other fish in the tank are acting normal.

I have done one treatment in the main tank (PraziPro liquid and MetroPlex) yesterday because of this behavior. No change. I don't want to throw the sink at him (or move him) without more specific symptoms. Any ideas are GREATLY appreciated.

Tank/water specifics :

- 8ft 240g, Temp 76-77. 3 FX6s and 3 sponge filters. Water change schedule is 75% every 3-4 days. (Been doing 50% daily since this behavior).
- Ammonia and Nitrite - 0, Nitrates - 5ppm. (Normal is 5-10ppm), GH 50ppm, KH 40ppm, PH 6.7

Thanks in advance!
 
Is he showing any physical symptoms? I had a melanura go through something very similar to the symptoms pf what you’re describing. The only difference was the base of his pectoral fins was inflamed. I spent around almost 9 months on/off treating him before ultimately euthanizing him.

 
Thanks for the reply HUKIT HUKIT

Zero physical symptoms. He looks great. I didn't get any responses here, so I made the executive decision to move him to a small hospital tank. Since then, I have treated him with Flubendazole for 2 days, and I am on day 2 of KanaPlex. Daily water changes while replacing the meds removed.

He has perked up a bit post-Flubendazole. He started attacking his reflection in the bottom glass, which was a great sign. Yesterday. He ate a few mini algae wafers, though he spit out Krill. Still, it was a good sign that he tried to eat. After a Kanaplex course, I may run another round of Flubendazole, due to the spitting.

Overall, there has been a small improvement, but I am monitoring closely. Thanks again for the reply.
 
I suppose it's possible, but I really just have pea gravel or larger rocks in my tank. Nothing in the middle. I tried a couple al algae wafers today, but he didnt go for it. I am going to water change tonight, and will eitehr do another round or Flubendazole, or switch to General Cure. Thanks for the reply....please keep em coming if any other thoughts pop up.
 
Thanks for checking in. Today is day 8 of force- feeding. Many thanks to HUKIT HUKIT for the recommendation to do so on an adjacent forum.

After day 2 of force feeding (with meds in the food for Hex), his behavior was noticeably improved. With that said, he still hasn't eaten in his own yet, but I'm sure I reset the stress click every time I meet him, place him on a pan, and stick a syringe in his mouth and down his throat. It is very stressful for me as well, and I hate doing it. But on the whole, it seems to have shown some benefit. My plan is to run a 10 day course.

Please keep your fingers crossed for my buddy. Thanks again

Yes. Thank you. After the daily force feeding regimen, I put him back in his tank, and he went right back to his spot, kicked the Pssiticus out, and dug out his hole. The next day, he started eating again.... though only worms. He spit dry food, but kept trying.

It's getting better daily, and he is able to get Small krill down, along with red wigglers.

Thank you for your concern.
