Got four longfin black tiger Oscars, around 10cm in the big tank and just today got some longfin albino tigers however they are only around 6cm. What's the best way to get them up to size and then introduce them into the big boy tank?

Cheers,
Richard.
 
I always change decorations while introducing. Resets all territories, your new Oscars will still get agro while your fish re-establish; but no way near as much bullying as they'd get as entering an established system

When I was about 9 my dad bought me a new tank after I had already had a oscar who was a female for about 6 years I think. We bought 2 tiger oscars and just dropped them in and the 6 yo just swam along with them side by side. One of the Tigers and my older albino tiger spawned a few years later and didn't get aggressive with the other oscar either.
 
Depends on the Oscars, honestly. Mine is pretty relaxed I can introduce anything smaller than him and he won't bother it at all. If it's big or the same size as him he goes crazy and tries to kill it. No rearranging helps.
