Can Green Tiger Barb live with Marbled Crayfish?
Caution — with care
Why
- Marbled Crayfish can grab Green Tiger Barb while it sleeps — only fast mid/top-water fish are reasonably safe.
- Green 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.

How to make it work
- Only combine with fast, mid/top-water fish and give the tankmates plenty of escape routes.
- Keep the nipper in a bigger group (8+) to spread out the nipping, and avoid long-finned tankmates.
