The disappearance of coral reefs from our planet could lead to a domino effect of mass destruction. Many marine species will vanish after their only source of food disappears forever. There might be an acute food crisis in coastal regions, as a number of fish begin to die off.

What Do Coral Reefs Need to Survive?
- Sunlight: Corals need to grow in shallow water where sunlight can reach them.
- Clear water: Corals need clear water that lets sunlight through; they don’t thrive well when the water is opaque.
- Warm water temperature: Reef-building corals require warm water conditions to survive.
Where are coral reefs dying?
Many South Pacific reefs experienced their worst-ever bleaching, and “reefs in the northern part of Australia’s Great Barrier Reef that had never bleached before lost nearly 30% of their shallow water corals in 2016, while reefs a bit farther south lost another 22% in 2017,” it continues.

- 3 The Chili Coral.
- 4 The Sun Coral.
Can you keep hard and soft corals together?
Because of their differences in light, flow, reef habitat, feeding and aggressiveness, LPS and SPS corals shouldn’t be kept together. Few tanks are large enough to dedicate different zones of light colour temperature and flow patterns, so have either soft corals, LPS or SPS, and provide conditions particular to them.
Can coral grow inside you?
This has led one diver to ask me, “Can coral polyps grow in my skin?” The short answer is, “No, it is not physiologically possible for coral, hydroid or sponge cells to live on or within the human body.” This constellation of requirements is extremely unlikely to exist on or within the body.
Are corals dangerous?
Species of Zoanthid coral (e.g. Palythoa species and Zoanthus species) can contain a highly toxic, naturally-occurring and potentially lethal substance known as Palytoxin. Zoanthid corals are often recommended to new marine aquarium owners because they are considered to be relatively easy to keep.
Is it OK to touch coral?
Don’t touch! Corals are fragile animals. Be careful not to touch, kick or stand on the corals you see in the water because this may damage or even kill them.
Does fragging hurt corals?
Corals rely on nature to do the “fragging” in the wild – stormy seas will break off pieces of colonies which will then be able to start growing elsewhere. When you frag a coral, you’re simply dividing up the colony – it’s not the same as lopping a rabbit’s foot off!

Why won’t my toadstool coral open?
Toadstools will develop a waxy coating on the surface, this enables the coral to shed any detritus or algae build up. During this period the coral often remains closed until the waxy coating is shed. Double check your water chemistry though. Increasing flow may assist the coral in shedding the coating quicker.
How much light does a toadstool coral need?
Lighting & Flow Requirements: The Toadstool Leather requires moderate water flow and low to moderate lighting (PAR 80-250). T5’s, Metal Halides, or LED’s can all grow Leather Corals when the proper PAR levels are provided. We recommend a 14-20K color spectrum for best coloration.
