For a couple days now, my oscars have been acting weird. Jr. my 8in oscar has been opening its mouth alot, towards his fellow oscar and also to me and the glass for no reason. He also pushes/bumps into the other oscar.

Another thing to add is that I bought some different pellets and tired to feed both of my oscars but only one eats it(Mimi a 6/7in oscar) and jr doesnt but eats milworms. But when I got him his food(hikari pellets) he eats it spits it out and eats it agian. And to add to this he also flares up his gills and keeps it like that some times for about a couple of secs.

Now what both of my oscars they tend to swim normals and then every now and then their rear fin like twitches for like a sec.

Is their something wrong with my fish??
 
They might be wanting to breed. You described nothing to worry about.

Pellets spitting is normal when trying new food.

One of them is turning, so it seems, into a glass banger. I like it.
 
My Oscar did this too. With his mouth open he would twitch and shake and also while he was doing this his color would change.

Change colors??
 
Sounds like mating ritual to me, my Dempsey's do this to each other when they're about to spawn. Glass banger is a term used to describe a fish that attacks the glass when someone approaches or it sees itself thinking there is another fish in the tank. As far as food goes, cichlids seem to be notorious for making a mess with their food. Oscar's more than any other seem to pout over not getting what they want to eat, but don't let that cause you to only feed them one kind of food. Keep feeding the pellets and if anything don't offer the mealworms or other treats for a while.

Are they digging pits in the substrate?

What no treats for them?? =(

And not so far but I can say that all the other fish are scared.

Continuing to feed the treats will spoil them to the point they wont want to eat the other food.

If they've got the other fish scared, it sounds like they're going to breed. If they start digging in the substrate, you might want to divide them from the rest of the fish if possible. When they spawn they'll protect their babies with their lives. If any of the tank mates get near them, they will attack them. I don't know about Oscar's but I know my female Dempsey turns into a complete lunatic when she lays eggs. Attacks anything that gets near them.
