How much flow do zoanthids need?

How much flow do zoanthids need?

Zoanthids are generally placed in the bottom three quarters of the tank in an area of moderate flow. Too much flow will cause the polyps to retract and too little flow will encourage algae-growth may smother the corals with insufficient oxygen.

What type of flow do zoanthids like?

Zoanthids prefer a low flow. Too much flow can make it difficult for polyps to open up. In fact, if the polyps are closed, too much flow is typically one of the first things to check.

How do I make my zoas bigger?

Zoa addict Making polyps bigger has to do with lighting and placement. Get a par meter, in my tank at around 100-150 par everythin is bigger. But some like vivid rainbows like 300 par to be bigger. Bloodshots get bigger at 60-75 par.

How fast do zoas spread?

Depends on the zoas I think. Most of mine grow at about a polyp every few weeks. However, I have a colony that is not invasive by nature but is growing about 1 polyp a day!

How do I care for my Zoas?

Some types of zoas like more light, some less. Experiment until you find the perfect position. When it comes to water flow, moderation is the key. Too much flow can cause retraction of the polyps, too little and the zoas will receive fewer nutrients through the water.

Can Zoas grow in high flow areas?

Though zoas grown in your tank should not be exposed to high flow-areas to ensure steady growth, zoas in nature are often exposed to strong waves and thus grow shorter and more spread out. Your zoa garden may look this way if left in a high flow area.

What is the best flow for zoanthids?

Low to medium flow is key for zoanthids. You need enough flow to keep their mat clean of debris, which can irritate the coral if left unchecked, but they do not tolerate being blown around in heavy coral, as they are soft corals without much of a structure. Too much flow will make them close up for their own protection.

What is ZOA pox?

Zoa pox is the name given to the zoanthid disease characterized by tiny growths on the side of affected zoas. I’m not sure whether the growths/pustules themselves irritate the polyps and cause them to close up or if the coral is otherwise sickly and closed up (therefore showing the zoa pox).
