IT being a menace to society

Of my tank lol it went nuts after i rearranged things (usually do it once every couple weeks).. he flys after my Orino pbass and balzani geo, and just doesnt let up. He wasnt nipping, just chasing but not the fins of my O are starting to look torn so hes nipping now.

I know there are a few threads on dat aggression but my situation is different then the others ive seen, my dat is only 4 inch and is causing all this ruckus. Even my red wolf doesnt go after him, and he normally kills things that are like this. Not even a nip on the dat.

Tank is a 70 ga long (upgrading in spring to at least 200 gallons, already gathering supplies) tank mates are

-leopard ctenopoma (who the IT ignores now but used to beat up on)
-Balzani gymno
-Red wolf fish
-Ornate Bichir
-palmas polli bichir
-palmas beuttokoferri bichir
-ropefish
-Orino pbass

He leaves the ropefish and bichirs alone, and faces down my red wolf on occasion. Did not expect this little guy to pack such an attitude. Is it the consistent rescaping? Or tank size? Or just a mean dat lol? Trying to add some dithers soon, any reccomendations to keep the dats attention?

Hmm would one more be bad? I'm adding a bicuda and azul pbass soon and don't want to be insanely overstocked haha

alright im going to not rearrange things so much lol see if that helps at least wasnt sure if dats did claim territory and such, once the azul is on pellets and buffed up a bit hes going into the 70 so that will help. Im sure the Bicuda will help distract too. I am upgrading lol in like febuary so things will be ok till then. if its not, i have a 30 ga i can toss some aggressors in temporarily. Once he settled in this guy took over, i hope my red wolf doesnt decide hes had enough of him one day
