Can Siamese Algae Eater live with Three Spot / Blue Gourami?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Three Spot / Blue Gourami is semi-aggressive and may bully the peaceful Siamese Algae Eater — give lots of space and cover.
Sweet spot: both do well at 73–79°F and pH 6.5–7.6 — aim there.
