Can Guppy live with Siamese Algae Eater?
Caution — with care
Why
- Siamese Algae Eater may eat Guppy; add only full-grown adults, because juveniles and fry will be picked off.
- No overlapping water hardness: Guppy wants 8–20 dGH but Siamese Algae Eater wants 6–7.5 dGH.
Sweet spot: both do well at 72–79°F and pH 6.8–7.6 — aim there.
