Gorgonians can be divided into two categories, photosynthetic and non-photosynthetic. Photosynthetic gorgonians require good lighting at moderate levels to thrive. Non-photosynthetic gorgonians get their sustenance through filter feeding by their polyps. This can be done by feeding phytoplankton, baby brine shrimp or detritus by stirring up the substrate at least once a week. Both types of coral require good water movement and pulsating flows are preferred. If algae accumulates on a gorgonian, remove immediately as algae can cause tissue deterioration. When transporting, keep exposure to air at an absolute minimum. Gorgonians are a unique species and are an excellent way...

Palytoxins exist in some soft corals called polyps and are common in the hobby, but poisoning from them is extremely rare and is easily avoidable. The toxin is used as defense mechanism for this coral and they should be viewed as an animal. When they are exposed to conditions that are deadly to them, they can release the toxin, but these don’t happen under normal circumstances. Exposure to the toxin can happen if the polyps are left in air for extended periods of time, exposed to extreme heat, are cut out of water, or are consumed as food. None of...

Corals, Phosphates -

Are your fish looking plump and happy but your corals aren’t opening or dying off? In this scenario, you might want to look at your phosphate levels. Phosphates come from biological waste from your fish and leftover food but they can also come from other sources like tap water. They act like a fertilizer for pest algae which can takeover a tank. Phosphates also inhibit coral growth by reducing the amount of calcium they absorb and can turn corals brown as the cells become overrun by brown algae. Hardy corals like softies can handle 0.25 ppm of phosphate, while SPS...
