i noticed that when my Os flare up and get fiesty, they have yellow strips that glow like crazy and i thought that is was a color transformation but its not constant. the yellow calms down when they r fine but once in a while when their fins flare, that yellow just brightens rit up, anyone elses do that?

Yes mine do that as well, except it is their Orange that gets brighter.

is your oscar doing something similar to this video?

its perfectly normal, mine does this all the time.

Lol, I tried the trick with the mirror once and scared my oscar whitless!
He did not like that at all...
But he changed colour allright.

i think so, but its not the orange that brightens, its weird, they r tiger Os so its hard to say if its the same as the vid angmat provided, but they have 3 dull thick "tiger" stripes down their backs, and when they get frisky it just lights right up, but im sure its the same as everyone elses. thanks for the replys

I expect it is just trying to make itself look bigger and even maybe fiercer, stand out in the crowd so to speak. Reminds me very much of squid and cuttlefish

He's trying to be macho, the female O's can't resist it
