Zoanthid polyps are usually sold as a colony, however we do bring in a few zoa frags when rare ones are available at a great price. Colony rocks usually start at $18.00 for small rocks and large rocks can be over $150.00 (Rainbow rocks that include more than just zoanthids. These rocks usually have green star polyps, yellow polyps, bright red or pink polyps, sand polyps and much more). Zoanthids can handle all ranges of lighting.
Mushrooms are usually sold as colonies and not singles. Mushroom rocks start at $18.00 for small rocks with common mushrooms while larger rocks or ones with rare mushrooms can be $50.00 or more. Most mushrooms can handle low to moderate lighting, but a few species prefer high intensity lighting.
Clams vary greatly depending on species. Small Croceas can start around $36.00 and up when in peak season. Squamosas are also available upon request. Typically Clams want as much light as they can get and are best placed on the bottom on the sand to avoid injuries.
Frogspawn is a very popular coral that starts at $36.00 for small colonies and can top $89.00 for very large colonies. This coral is not stocked all the time. High intensity lighting is what this corals wants.
Acropora like so many other corals varies in price. Medium size starts around $39.00. High intensity lighting is a must for most species but some will do OK with moderate lighting.
In order for your coral to live, you will need to know how to feed it. Most corals need adequate lighting to "activate" the zooxanthellae that resides in the corals body. Photosynthetic corals use this zooxanthellae to feed. Some corals are non-photosynthetic which means that they must capture their own food. These corals benefit from plankton and other forms of food.
Corals in an aquarium must be properly positioned in order to have a chance at living. Light, food and current is what plays the role of success or death in the aquarium world. Too much or too little light can keep the coral from feeding on the zooxanthellae. Lack of food (plankton, krill etc) and the coral may starve. Too little water current and the coral may never extend it's polyps. Too much and tissue damage may occur.
Corals require great water quality. In fact, some corals will perish in hours if the parameters are too far off. Proper Specific Gravity level of around 1.024 - 1.026 is required. 0 Nitrates, 0 Nitrite, 0 Ammonia, 0 Phosphate are all desired levels. These levels are not always possible but keeping them at or near will yield best results.
