Stock-Photo Coral
This is NOT A WYSIWYG listing, but we make it as close to one as possible. The photograph shows either the exact mother colony from which your coral originates or a representative frag displaying the size and presentation standard you can expect to receive.
In both cases, your coral comes from the exact named lineage shown. Every piece is individually selected and fully conditioned before shipping. Because coral is living and continually growing, natural differences in shape and growth may occur.

Cosmic Grape Hammer Care Guide
Cosmic Grape Hammer is a hammer, frogspawn, or octospawn coral that prefers moderate light, indirect flow, and room to expand without touching neighboring corals.
- Care level
- Moderate
- Suggested PAR
- 75–175
- Water flow
- Moderate, indirect
- Placement
- Lower to middle reef
- Aggression
- High
- Feeding
- Optional, up to weekly
What Cosmic Grape Hammer needs
Use varied, indirect flow that moves the tentacles without whipping them. Avoid sharp rock contact with inflated tissue and leave several inches between colonies. A slow light acclimation is safer than placing a new specimen at its final intensity on day one.
Stable water targets
Use these as a steady operating range, not numbers to chase from day to day.
- Temperature
- 76–79°F
- Salinity
- 1.025–1.026 SG
- Alkalinity
- 8–9 dKH
- Calcium
- 420–450 ppm
- Magnesium
- 1300–1400 ppm
- Nitrate
- 5–15 ppm
- Phosphate
- 0.03–0.10 ppm
How to acclimate Cosmic Grape Hammer
- Inspect the bag and coral on arrival. Photograph any shipping concern before opening the bag, then follow the store's live-arrival instructions.
- Match temperature, inspect the coral under white light, and use a coral dip that is appropriate for the coral group. Do not add shipping water to the display.
- Begin below the final light intensity for the first several days. Move or raise intensity gradually while watching tissue and polyp response.
Cosmic Grape Hammer care questions
Where should I place Cosmic Grape Hammer?
Start at Lower to middle reef. Leave room for growth and move the coral only after observing its response to the current position.
How much flow does Cosmic Grape Hammer need?
Use Moderate, indirect flow. The goal is steady gas exchange and debris removal without folded tissue, exposed skeleton, or polyps held in one direction.
Should I feed Cosmic Grape Hammer?
Recommended frequency: Optional, up to weekly. Feed only when the coral shows a response, use appropriately sized food, and remove uneaten food before it irritates the tissue.
