help oscar stayin at top tank??????
 

my oscar keeps coming up to the top alot and sticking his head out the water and i dont knw why is he ok or wuts up with him he never does this :-?

What's your water parameters, nitrites, nitrates, ammonia ect?

how big are the fish in your aquarium, you have monsters in there! agree with rohland need some water params.

idk i dont use thos things never have im more old school lol the fish arnt monsters at all lol

you should be checking the parameters of the tank, you might be surprised at how bad they are. i've read your other post and you should take the advise that the others have given. test your water, get bigger tank or rehome your fish.
