Can Guppy Live With Peacock Gudgeon?
Yes, guppies and peacock gudgeons share a tank well in 15 gallons or larger, and both species are peaceful community fish with overlapping care needs.
Why
- Guppies are 1.5-2.5 inches. Peacock gudgeons reach 2 inches. Size parity prevents predation.
- Peacock gudgeons prefer the lower-to-middle water column. Guppies tend to occupy the upper levels. Separate swim zones reduce interaction.
- Both species thrive at 74-79°F and pH 7.0-7.5, a range that suits most community setups.
- Peacock gudgeons are not aggressive toward tankmates. Male guppies may display to each other, not to the gudgeons.
What could go wrong
Male guppies with elaborate fins may attract unwanted attention from peacock gudgeons during feeding, though physical damage is rare.
