Can Koi Angelfish live with Typhoon Pleco?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Typhoon Pleco is semi-aggressive — give the peaceful Koi Angelfish plenty of space, cover and broken sight lines.
Sweet spot: both do well at 78–84°F and pH 6.5–7.5 — aim there.

How to make it work

- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
