Can Neon Tetra Live With Peacock Gudgeon?
Yes, neon tetras and peacock gudgeons coexist peacefully in 15 gallons or larger because both are small, calm fish with overlapping care needs.
Why
- Peacock gudgeons grow to 2-3 inches and are peaceful bottom to mid-water dwellers that rarely bother other fish.
- Neon tetras stay at 1.5 inches and school tightly in the middle water column, keeping them out of the gudgeons space.
- Both species thrive in temperatures of 74-79F and slightly acidic water around pH 6.0-7.0.
- Peacock gudgeons are not fast swimmers and cannot catch tetras even if they tried.
- Neither species is nippy, and the size difference is modest enough that predation does not occur.
What could go wrong
Peacock gudgeons may compete aggressively for food at feeding time, so target feeding helps ensure tetras get their share.
