Can Guppy live with Siamese Algae Eater?
Caution — with care
Why
- No overlapping water hardness: Guppy wants 8–20 dGH but Siamese Algae Eater wants 6–7.5 dGH.
- Large size gap (Siamese Algae Eater 6" vs Guppy 2") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 72–79°F and pH 6.8–7.6 — aim there.
