Can Blue Lobster Crayfish live with Discus?
Caution — with care
Why
- Blue Lobster Crayfish can grab Discus while it sleeps — only fast mid/top-water fish are reasonably safe.
- Almost no shared temperature: Blue Lobster Crayfish wants 65–82°F and Discus wants 82–88°F, so only 82°F suits both — too fine a margin to actually hold.
Sweet spot: both do well at 82–82°F and pH 6.5–7 — aim there.
Side-by-side
| Blue Lobster Crayfish | Discus | |
|---|---|---|
| Temperature | 65–82°F | 82–88°F |
| pH | 6.5–8 | 5.5–7 |
| Hardness (GH) | 5–20 dGH | 1–8 dGH |
| Adult size | 5" | 8" |
| Temperament | Aggressive | Peaceful |
| Min tank | 30 gal | 55 gal |
Together, plan on at least 55 gallons.
How to make it work
- Only combine with fast, mid/top-water fish and give the tankmates plenty of escape routes.
- Target the overlapping water-parameter range and acclimate slowly.
Sort it with: An adjustable heater
