What can be done if this is the case? He has not pooped for almost 2 days and is not acting himself, jerking really hard to the point of flipping over, not able to grab food to eat and bumping into everything in tank.

theres not much you can do. sorry. either it will pass teh stone, or it will die.

it sucks, sorry

Check again and try to take them out with a pair of tweezers

I have read all your posts, and it seems to me you are grasping at straws to try and "Guess" what is wrong with your fish.

We need EXACT water parameters. For ammonia, nitrite, and nitrate.

Until we get that info, nobody can help.

okay, I just checked the water and these are the results according to the new testing strips I bought yesterday.

GH was 180
KH was 240
PH was 7.0
Nitrite was 0.5
Nitrate was 0

I have been praying and reading all night. Based on what I have read from different websites, my oscar sure acts as though it were a swim bladder problem. What do you think? Such as Erratic Swimming Position, Loss of equilibrium, Fish will be unable to maintain buoyancy

Please give me your thoughts. I am going to get it peas, placed tablets for the "all in one treatment" and was going to go get some natural eating plants for oscars.
I did add 1 1/2 teaspoons per gallon of salt to the tank as well.

Please make suggestions. Thanks!

dont and salt as this wont make a difference to anything, dont panic treat ull make it worse your nitrite should allways be 0.0 even 0.5 can cause serius problems, i,d do a 50% water change and monitor him over the next couple of days, use a stress coat like APR in water change. if no better and no solution there are some very good fish vets out there depends how far u want to go. can,t c ur oscar swolling a stone and getting it stuck this is rare. poisioning fitts the symptons have u got an air freshner near the tank? remember fish problems 90% water nearly allways.

Thank you all for all your help and suggestions. I did go visit and called a fish expert. She knew immediately all the symptoms before I could finish. She suggested the following:

Melafix and Pimafix and to continue the water tablets I started. She knew about the vision problem, the tail jerking and his struggle with eating. She also said to give him some of his pellets along with the peas in order to keep some familiar foods for him. She also thought that since I had just given them live crickets that there was a great possibility that as the cricket struggled inside of him (since they swallow them live), that the cricket ripped some of his insides. She mentioned that if there were any rips in his inside scales, it would start affecting his tail first. She suggested the two meds for 7 straight days, then do a 25% change and if i don't see a significant change to do 7 more days and that should take care of the problem. She even knew the eye that he lost his vision from. She called it "eye cloud". I pray all this works. Thanks again yall!

first time to hear that a cricket could harm an oscar just like that...
i could not imagine that little creature could still kicked inside an
oscar... oscar has a very strong throat muscle and the cricket should
had been squeezed to death before swallowing.... i doubted the allegation.

nevertheless...good luck...hope the lfs suggestion works for you....

I hope this works and please keep us posted, its a new one to me and i would like to know if it works
