New guinea red rainbowfish ,male, good fish, average 5-6 inches,omnivore,loves frozen livefoods like bloodworm and the females in particular like browsing the odd bit og blanched lettuce. Shoaling fish, reasonable fish for 135 litres, though a 4 footer would be better ,could do with 5 more really. Got some myself.
Very sexual species, most rainbows are, they live for courtship and display, a perfect mini shoal would be 2 males, 4 females so the females dont get too stressed by all the attention. Males usually like at least one other male to spar with, its mostly ritual.At least being so sexually dimorphic (males different colour from females) its a doddle to sex them.
