Can Guppy Live With Neon tetra?

Detailed assessment

Both Guppy and Neon tetra share a comfortable temperature range of 22–25°C (Guppy prefers 22–28°C, Neon tetra prefers 21–25°C). Their pH ranges overlap well at 7–7, so water chemistry is compatible. Both species have low aggression scores (Guppy: 1, Neon tetra: 1 out of 10), which supports peaceful cohabitation. Note: fish 2x+ larger may eat smaller tankmates species with non-overlapping ph ranges may not thrive together With careful monitoring and adequate tank size these species can usually coexist, but be prepared to separate them if aggression or stress appears.
