Neon coral is an exquisite addition to any reef aquarium. These vibrant blooms glow green under actinic lights, making a striking statement against dark backgrounds. Neon coral requires little care and maintenance and thrives well in most tanks; making it an excellent beginner choice! These corals may not grow as rapidly as Favites or Acropora species, yet will still flourish under your system’s conditions.
Coral reefs are underwater rainforests, providing shelter and nourishment to marine creatures while absorbing carbon dioxide and waste products in exchange for shelter, food and other essential nutrients. But with global warming wreaking havoc, rising ocean temperatures may cause coral animals to expel photosynthetic algae they rely on for survival, leading to their bleaching. But some corals seem to be defying this trend.
Study findings published this week in Current Biology have revealed that some corals develop neon colors during bleaching instead of losing all color altogether. Researchers don’t fully understand why this happens but speculate it might be in order to attract back their symbiotic algae colonies – almost like coral version of sunscreen; colorful pigments act as protective layers against UV radiation, while simultaneously drawing algae back towards their skeletons.
Researchers conducted an in-depth survey from 2010-2019 of corals that had turned neon, and determined that their colors typically appear 2-3 weeks following a bleaching event, such as prolonged warm temperatures or temperature spikes. Without algae present to absorb UV rays, corals become much more vulnerable to UV damage from both natural light sources as well as ambient ambient lights in water bodies such as oceans or rivers.
As a way of counteracting this effect, neon corals produce additional pigments to absorb UV rays – similar to how humans use sunscreen protection – and it appears to work just as efficiently.
Corals that turn neon are still at risk of bleaching and death despite their vivid hue. Therefore, it is vital that their tanks remain at an ideal temperature while minimizing sudden water changes; but it’s encouraging that some corals are making attempts at self-protection against climate change; even if this approach can’t completely overcome climate change alone.
Neon Green Favia Coral
This vibrant coral has a beige base with vibrant neon green polyps that will liven up any reef aquarium. Favia corals are also commonly known as Moon, Pineapple, Brain, Closed Brain Star Worm Honeycomb corals – although many aquarists have had great success keeping LPS varieties like this alive in tanks! However, to maintain them successfully it requires ample room between it and other corals; carbon treatment should also be implemented periodically in the tank to prevent it from emitting toxic compounds into the tank which could inhibit growth of stony corals as toxins could release and inhibit their growth as stonys may inhibit their growth as stonys grow slower over time than normal.
