Can Siamese Algae Eater live with Purple Vampire Crab?
Caution — with care
Why
- Purple Vampire Crab can grab Siamese Algae Eater while it sleeps — only fast mid/top-water fish are reasonably safe.
- No overlapping water hardness: Siamese Algae Eater wants 6–7.5 dGH but Purple Vampire Crab wants 8–15 dGH.
- Only a narrow pH overlap — keep both around 7.5–7.6.
Sweet spot: both do well at 75–79°F and pH 7.5–7.6 — aim there.
