"WYSIWYG" ("What You See Is What You Get") - Coral Original Images.
To make sure you get exactly the coral you want, every single coral is photographed by us. And usually once under daylight illumination and once under blue light.

If you have any further questions, please check our Fauna Marin Support Forum and our  Fauna Marin Reefing Group at Facebook.

General information of  Acropora SPS-corals:

  • Tank:
    >200 Liter

Keeping of sps corals ( SPS  = Small Polyp Stoney Coral) is possible with today's technology, such as with the use of, for example, the  Fauna Marin Balling Light method and the  Zeolight System.

If you provide the right current, good lighting and the  right water values, successful keeping of SPS-corals with good growth and great colors is feasible in a marine aquarium.


In contrast to LPS corals ( LPS =  Large Polyp Stoney Coral  ), which usually cope well even with higher nutrient values, sps corals quickly show a loss of color or stagnating growth. Formerly colorful corals often turn an unsightly brown. This is because of the higher nutrients in the water, which promotes zooxanthellae growth in the coral.

SPS corals love clean and clear water. In order to keep SPS corals almost in their natural colors on a long-term basis, you should strive for the lowest possible phosphate and nitrate value in the aquarium.

To successfully maintain corals in the long term, stable water and nutrient levels should be aimed for.
This can be well controlled with various  phosphate adsorbers. With filtration via activated carbon, such as  Fauna Marin Carb L long-life carbon, the water remains crystal clear. Phenols, protein compounds, dyes and nettle toxins are filtered out of the water and rendered harmless.  

Light intensity also affects the coloration and growth of the corals. At Fauna Marin Corals we successfully keep our corals under a mix of T5 tubes (50/50 white/blue), in combination with the  LED lamps.

Important for the care of small polyp stone corals is the constant maintenance of the salinity, as well as the use of a good sea salt, such as the  Fauna Marin Professional Sea Salt. The salinity should always be between 34/35 per mille, respectively 1.022 and 1.024 density. 

A regular check of the density is an absolute must in marine aquaristics. Our  salt calculator helps to calculate the correct amount of salt.

Pay attention - especially in summer - to the temperature in the aquarium. Corals do not tolerate temperatures exceeding 30 degrees for longer periods of time. If this is the case the corals fade, which leads to the so-called Coral Bleaching.

We recommend a regular control of the water values with our  ICP water analysis
Based on the results of the analysis, the water values can be adjusted correctly with the help of our dosage recommendations on our  laboratory website.

Technical data

***We will never ship freshly cut coral !***
We take great care to ensure the well being of all our corals. Before pieces are deemed saleable, we wait for every piece to have formed an encrusting edge and even develop baby polyps. As a professional supplier of quality frags in Germany, we differ significantly from our competitors. Our care and breeding practices for these wonderful corals make it possible to bring you the healthiest pieces available. The biggest difference, is in the regular feeding of the polyps; we feed LPS Grow and Color Food from Fauna Marin . All corals are prepared under optimum conditions to a healthy aquarium life and we consider this to be the optimum color formation under LED or blue T5 lighting.

***General Information:***
Due to the unknown variables that can happen during shipping, we cannot provide a 100% arrive alive guarantee for live animals , despite all efforts.

New orders begin processing the moment we receive them. Very rarely do we encounter a delay. If we do, and your corals or fish are not yet ready for dispatch, you have the option for a possible replacement animal or a refund for the amount of an animal. In such cases, you will be contacted via phone (if we have your phone number) or email. Of course, we do everything possible to avoid such inconvenience from the start.

Please note that coral variations in form and color can occur in the original photo. Changes in color may also result from transport or due to the color representation on the computer screen . Our corals are lit with Radions G4 Pro and are photographed in these conditions. The colors of the animals may vary from our photos when placed in your aquarium, depending on the type of lighting used.

All animals undergo a minimum one-week quarantine and are free of parasites when delivered.

Our average water parameters are:
Salinity : 34-35 psu
Calcium : 400-420 mg/l
Magnesium : 1200-1250 mg/l
dkH : 7.5-8.0
Nitrate : 2-15 mg/l
Phosphate : 0.02-0.08 mg/l
Temperature : 23-25 ​​° C

In our facilities, we use the new sea salt " Professional Sea Salt " by Fauna Marin . We also use the Balling light method in addition to their sea salt.
We are professional pet shippers with over 20 years of shipping and packing experience. All corals and other animals are carefully placed into their packing box and prepared with care. We take great care preparing corals and other animals for a safe transport so that they arrive to you in perfect condition. It is not primarily about the color of the animal upon arrival, it is about the health and nutritional status of coral and fish. The final coloration reach corals within a few weeks after being placed into your aquarium.
