Ok, here's my problem: I have just moved my two tiger oscars from a 55 grow out tank into a 300 gallon. They are more aggressive in the 300 than they were in the 55! They are constantly chasing anyone and everyone they come across and I don't understand why! Below is a list of everyone in the 300:
2 tiger oscars6-7 inches
1 albino oscar 4 inches
Rhino pleco 7-8 inches
Jack dempsey 5 inches
Blood parrot 4 inches
Black ghost knife fish 8-9 inches
6 silver dollars 2-3 inches
The only one the oscars do not mess with is the knife fish. There are plenty of caves and 4 plants with pool filter sand as substrate, fx5 and 55 gallon sump as filtration.
