Tank Type: Moderate flow, moderate light, mid-level nutrients

Nutrient Behavior: Moderate nutrient levels support polyp inflation and feeding
Tank Role: Supports visual coral extension and passive feeding

Description

🔍 Description:
LPS tanks strike a balance between beauty and manageability. These corals enjoy moderate nutrients and flow, with large fleshy polyps that sway and extend. Clean-up crew selection should focus on gentle grazers that don’t bulldoze through coral colonies or disturb the sandbed too much.

What The Crew Focus On

✅ What This Crew Focuses On:

Algae Control: Rock, glass, and sand

Minimal Interference: Gentle enough not to topple fleshy corals

Support Polyp Feeding: Remove excess food without over-scavenging

Best Predator

🧽 Best Cleanup Crew for LPS Tanks:

Astrea Snails – effective rock and glass grazers

Nassarius Snails – scavengers that clean leftover food

Emerald Crabs – help control bubble algae and detritus

Blue-Leg Hermits – small and agile

Fighting Conch – great for sand without excessive movement

Notes

⚠️ Notes for Success:

Watch for Coral Bumping: Avoid large turbo snails or aggressive hermits

Target Feed When Needed: But clean up after

Mix of Sand and Rock Grazers: Maintain full coverage

Avoid Overcrowding: Too many grazers can disrupt coral extension

Pro tip

🧠 Pro Tip:
LPS tanks need just the right balance — clean, but not sterile. A calm, reliable crew lets your corals puff up and shine without stress.
