![]() Those chemicals have since been banned for sale and use in Palau. ![]() The island nation of Palau released a report in 2017 ( PDF) that says scientists detected harmful levels of 10 chemicals in Jellyfish Lake, a popular tourist attraction for swimming and water sports.Yet another study in 2017 speaks out against oxybenzone as a harmful compound to both humans and coral reefs, but again, uses laboratory data that may or may not reflect what's really happening to the coral reefs.This study was conducted in laboratory settings, which may or may not correlate to real-life settings. Another 2015 study replicated the findings of the above study, but this time with benzophenone-2 (another chemical in the same class as oxybenzone).This study was conducted in laboratory settings. A 2015 study found that oxybenzone directly contributed to bleaching of coral in both light and darkness, and that oxybenzone caused the planula (an important component of coral reproduction) to harden.However, the study involved direct application of sunscreens to corals and higher concentrations of sunscreen than found in natural settings, which doesn't represent real-life scenarios. In 2008, scientists concluded that sunscreens cause viral infections in corals, which resulted in rapid bleaching, leaving them susceptible to death, especially in corals subjected to higher water temperatures.To help you better understand the impacts of chemical sunscreen ingredients on coral reefs, here are the findings and limitations of some of the most widely cited studies on sunscreens and coral reef health: There's also come concern that one specific ingredient, octocrylene, can directly contribute to the death of coral reefs. Bleaching doesn't kill coral, but it does leave the coral at risk for infections and mortality. ![]() Scientists have found that some chemicals in sunscreen contribute to coral bleaching, a process by which coral reefs expel the colorful algae that lives in the corals' tissues. No matter the species, it is always a good idea to give all the corals in your tank plenty of space to grow and thrive.Bleaching of coral due to rising ocean temperatures and pollutants is a big concern for the environment. Be sure to stay wary and make sure to provide sufficient space for any established colony or colonies that may be near your choice in placement in the aquarium and the newly introduced Ricordea, Yuma Ricordea, and/or Mushroom Corals for them to thrive. Placing them on the sand bed could be problematic as well as you would run into other issues such as when siphoning the tank it is possible for the coral to be flung across the tank by accident and sometimes even without immediately noticing the disappearance of the coral which sometimes, depending on how established the aquarium is never to be seen again. Placing them low to mid-way in the tank seems to have the best results as too much light or flow can be a problematic for these types’ animals. They like substrate or little pieces of rock to hold onto. When try to decide on placement of the Ricordea, Yuma Ricordea, or Mushroom a lot of people would say place them on the sand bed and let the coral do the rest are best for placement in the aquarium However, I disagree with the people that state to place them on the sand bed. Ricordea Corals can handle higher nitrates than SPS or LPS corals. Every coral has its own Requirements so be sure to gather as much information regarding the coral to ensure all requirements have been met. Ricordea Corals are fairly tolerant to a wide range of lighting and flow conditions However, They do NOT like highly intense flow and lighting so placement in the aquarium needs to accommodate all the corals’ specific requirements and needs. Since they are part of the Anemone family, they have a “sticky foot” and they will uproot and “walk” around as they see fit until they either find a place they are happy with or they perish due to not finding a suitable place to call their home. It is very important to remember that Ricordea, Yuma Ricordea, and Mushroom corals are all in the Anemone family. They require supplemental feeding of small leafy foods like planktons, and brine shrimp, in addition to its diet of macro algae tissue. Ricordea are photosynthetic and carnivorous. The Ricordea Coral comes in several colorful combinations which including green, orange, yellow, blue, and purple with blue, orange or purple rings surrounding a contrasting middle color. Ricordea do NOT require a lot to keep them alive and well in your tank(s) as a bonus it’s not too complicated either which also makes them great for beginners. As most hobbyists know, Ricordea Corals are not overly aggressive and make very good tank mates to most established coral colonies and in any reef aquarium.
