Need some input on tank stocking

[Ian14]

125 gallon tank:

-10 inch dempsey
-Two 8 inch oscars
-6 silver dollars
-Pleco
-Tire track Eel

265 gallon tank:

-Five 6"+ Vieja's
-Six small clown loaches
-two jack dempseys, firemouth, green terror; all somewhat young
-small oscar
-pleco
-bichir

The 125 gallon has been up for about 9 months and I'm now starting to see a lot of aggression from the jack dempsey towards one the oscars, especially when the lights go off.. lots of splashing. So far no serious injuries just a few scratches here and there.

The 265 has been up for about 5 months now and the vieja are getting old enough to where territories are still being decided and lately I've started seeing territorial aggression between a few of the larger ones, both males but other than that everything is fine in there.

I know both are stocked heavily, I do water changes every two weeks and have tons of filtration. Even though the 6 silver dollars in the 125 aren't involved in the aggression, would it help if I moved them and/or the eel to the 265 by freeing up space in the 125 tank?

I'll put pictures up, thanks!

This is the 265. Oh and a small gourami that got in there, can't see to catch it with a net
