Can Tiger Barb live with Zebra Pleco?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 4–6 dGH.
- Tiger Barb is semi-aggressive — give the peaceful Zebra Pleco plenty of space, cover and broken sight lines.
Sweet spot: both do well at 79–82°F and pH 6–7.5 — aim there.

How to make it work
