I have a few Monster Fish so here I am! My tanks include one with 3 blood parrots approx. 5 inches each; another tank with 2 leporinus: "Big Guy" is 8 inches and "Little One" is 6 inches with two yellow Gouramis (2 and 3 inches) as their dither fish and the four get along just fine; my final tank, that doesn't have any Monster Fish in it, is a tiger barb tank.
