Start with your aquarium’s conditions
Consider tank age, lighting intensity, water movement, nutrient stability and available space. A coral that thrives in one area of a reef may struggle in another.
Match coral difficulty to your experience
New reef keepers generally benefit from hardy pieces that tolerate modest variation. Experienced hobbyists may be prepared for corals with narrower lighting, flow or chemistry requirements.
Use WYSIWYG photos carefully
WYSIWYG listings let you choose the exact piece shown. Compare its shape, growth pattern and visible size, while remembering that coral appearance can shift under different aquarium lighting and camera settings.
Plan for growth and compatibility
- Leave space between corals that can sting nearby livestock.
- Consider the mature size, not just the frag’s current size.
- Match placement to appropriate light and flow.
- Avoid crowding new pieces into unstable or shaded locations.
- Research compatibility before mixing unfamiliar species.
Review shipping before checkout
Confirm that someone can receive the package and that weather is suitable. Gem State Corals normally ships livestock Monday through Wednesday and may hold orders during unsafe conditions. Read the overnight shipping guide and delivery guide.
When a custom coral box makes sense
If you want help coordinating color, difficulty and placement, consider a custom reef box. Tell us about your aquarium and preferences so the selection can be built around your goals.
