Koi Red Tuxedo Guppy is a pond fish, not an aquarium fish — it reaches 60-90 cm and lives for decades. It needs a large pond with powerful filtration and aeration.
Care tips
A POND fish: an aquarium is only suitable for short-term grow-out.
Plan for a very large adult size and heavy filtration.
Tolerates cool water well; feed less as temperatures drop.
