Can Colombian Zebra Pleco live with Royal Pleco?
Caution — with care
Why
- Very different sizes (Royal Pleco 17" vs Colombian Zebra Pleco 3.5") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
Sweet spot: both do well at 77–82°F and pH 6.5–7.5 — aim there.
