Can Common Pleco live with Blue Gourami?
Caution — with care
Why
- Very different sizes (Common Pleco 24" vs Blue Gourami 5") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Blue Gourami is semi-aggressive — give the peaceful Common Pleco plenty of space, cover and broken sight lines.
Sweet spot: both do well at 72–82°F and pH 6–8 — aim there.
