Can Endlers guppy Live With Guppy?

Detailed assessment

Both Endlers guppy and Guppy share a comfortable temperature range of 24–28°C (Endlers guppy prefers 24–30°C, Guppy prefers 22–28°C). Their pH ranges overlap well at 7–8, so water chemistry is compatible. Both species have low aggression scores (Endlers guppy: 2, Guppy: 1 out of 10), which supports peaceful cohabitation. They occupy different water columns (Endlers guppy: all, Guppy: middle), which reduces direct competition for space. The size difference is significant: Guppy reaches 5 cm while Endlers guppy reaches only 2 cm, and the larger species may view the smaller one as prey. Note: fish 2x+ larger may eat smaller tankmates With careful monitoring and adequate tank size these species can usually coexist, but be prepared to separate them if aggression or stress appears.
