Can Marbled Crayfish live with Tiger Barb?
Caution — with care
Why
- Marbled Crayfish can grab Tiger Barb while it sleeps — only fast mid/top-water fish are reasonably safe.
- Tiger Barb is a fin-nipper and will shred the long/flowing fins of Marbled Crayfish.
Sweet spot: both do well at 74–77°F and pH 6.5–8 — aim there.

- Keep the nipper in a bigger group (8+) to spread out the nipping, and avoid long-finned tankmates.
