So I had one oscar and one pleco in my 35 gallon fish tank and they grew out of the tank so I moved them to a new 75 gallon tank with an undergravel filter and it's been about 3 weeks since I set it up and my oscar has been acting weird he is sometimes at the very top of the tank just sitting there or he is hiding at the bottom behind his rock and he also randomly starts ramming into the glass and swimming violently into it and flares out his gills and every few times he rams the glass he shakes his tail straight up and down like he's twitching. I was wondering if this is due to the stress of a new tank or maybe the tank isn't cycled properly? He also has a weird gray spot on his side where it looks like he has missing scales.

Starting with the basics what are your water parameters in the new tank? Did you use cycled media from the 35g tank to jump start the cycle? Ocellatus can be huge babies and will sulk after big changes. As far as the spot you’re concerned with please attach a picture or video.
