Could a 4 inch Queen Angelfish live with a 3 inch Emperor Angel in the same 120 gallon tank just by themselves with no other fish with them and lots of live rock.thanx
Don't know much about full size angels (I stick to the little cherubs *dwarfs* myself) but I consulted my marine encyclopedia and it states that the Queen Angel is noted for aggressive behavior especially toward other Angel species.
Also states they grow quite large (up to 18 inches).
The Emperor has a more peaceful reputation. It's labled as "inquisitive". Encyclopedia states they grow to about 14 inches. Also states that the Emperor is extremely intolerant of any declining water conditions. Ultra sensitive I guess.
I can't speak from experience with these fish, but from what I have just read I would do more research before putting them together.
