Clove Polyps Not Opening [ Detailed Discussion]

It cannot be very clear when your clove polyps aren’t opening within days. It was supposed to open before that. 

Why are clove polyps not opening?

This could be due to the insufficient flow of water. It can be because of lightning. Or improper placement in the tank. Or improper water perimeters.

Too much Alkalinity in the water can be another reason. Maybe some fish are making it uncomfortable. Or it can be because it has Critters Crawling on them. 

How Long It’ll Take To Open A Clove Polyp?

Clove Polyps are an incredibly beautiful and rapidly growing soft coral. In many ways, it’s comparable to a Xenia and a Pipe Organ.

They have soft fluffy polyps with an orangish or colored highlight on them. They upon a tube from which the stalk extends.

Many reef owners like clove polyps because they grow too quickly for their tank. They’re a relatively simple coral to frag, even though they are tough and hardy.

They don’t always open up to the full extent they ought to. Most of the time, clove polyps are vivid and enjoy flowing in the flowing water.

On average, all such coral reefs will open for up to twenty-four hours.

Several factors influence the time it takes clove polyp corals to open. Important considerations include water quality, lighting, movement of water, and tank placement.

This isn’t always the situation, and there are a few explanations why they might not be as forthcoming as they could be.

9 Reasons Why a Clove Polyp Not Opening 

Clove polyps are easy to frag, and they are easy to maintain. They can, however, be a little spectacular in certain cases.

And there can be plenty of possibilities why clove polyps are not opening like Duncan coral

I’ve mentioned several of the most appropriate reasons for their refusal to open up in this article, along with what you should do about that matter.

Let’s jump on to the main discussion. 

Reason 01: Too Much/ Too Low Water Flow

The amount of water flowing through the water reservoir is a huge factor in deciding how a coral reacts for most corals.

The clove polyp’s overall health is determined by the flow of water.

Although clove polyps do not require a lot of water flow, they’ll require a medium flow rate.

They may remain closed and not open when they do not obtain a sufficient volume of water flow.

Their tentacles may remain retracted if there is too much or too little water flow. Clove polyps prefer pulsing or variable flow rates of water.

For water flow, a simple air stone or air pump can be added to the tank.

It is constantly flowing water that is too strong. Or is aimed directly at the coral can also prevent it from opening.

Reason 02: Lighting

A lighting issue is another explanation for why a clove polyp won’t show up.

Clove polyp corals prefer low-light conditions. High lighting can cause stress, causing them to fail to open properly.

Place them in the tank where they will receive moderate lighting.

Several clove polyp corals might very well flourish in the tank. Where the light isn’t directly going to shine on them.

Reason 03: Improper Placement In The Tank

Clove polyps will thrive if they are placed in the appropriate area of the tank.

It’s wise to keep those in the center of the tank, which they can get aside from the bright lights and the constant flow of water.

Clove polyps enjoy being placed on top of rocks. If you have a tiny snippet of clove polyp, you can place it on the stone or in a pit or crevice, and it will grow onto the rock naturally.

Reason 04: Change In Water Parameters

It makes no difference whether you’re discussing corals or saltwater fish. It’s critical to maintain as stable a set of water quality as possible. Constantly shifting parameters can cause stress in animals.

Once they’re overwhelmed, it’s easy to tell. Weather clove polyps or bubble coral improper water perimeter can be harmful also. 

Clove polyps will demonstrate this by refusing to open. I’ve described the proper water parameters for clove polyps below.

Perimeters  Scale 
Salinity  1.025 
Temperature  76- 81° F
Calcium  400- 450 PPM
Alkalinity  8- 11 dkh 
Magnesium 1200- 1350 PPM 

Changes in water parameters can occasionally prevent clove polyps from fully opening.

For example, evaporated water that isn’t replaced could cause a change in salinity, affecting the clove polyp. As a result, you must maintain a proper water perimeter.

Reason 05: Get Accustomed to a New Tank

Suppose you’re adding a new clove polyp coral to your aquarium. They frequently shut themself down for long durations.

It usually takes some time for them to adjust to their new environment.

It is critical to acclimate new corals properly. They usually begin to open up gradually as they become accustomed to their new surroundings.

Reason 06: Critters Crawling On Them

On clove polyp coral reefs, mollusks and other lifeforms were seen slithering. For them, this can be a cause of anxiety.

Clove polyp corals can be crawled around by relatively clean prawns, recluse crabs, and a wide range of other animals. As a result, they are less open than they might generally be.

Reason 07: Moved To A New Location In The Tank

Clove polyps will immediately close up if you move them to a different place in the tank.

When you pick them up, they usually close up until they are put down and become comfortable again.

When you remove the coral from the water, it will quickly close up.

Reason 08: Water Changes And Tank Maintenance

Clove polyp corals can close up when you perform routine maintenance on the tank-like liquid changes and clean up the glass.

When sapping water from the reservoir, you may notice that if a piece of cleaning equipment is close to the coral, it will close and not open.

Reason 09: Disturbed By Fish 

You may have fish that like to nibble on algae on rocks. This can be stressful for clove polyp corals that are put on stones.

Fish like Yellow Tangs, dragonflies, and angels. All of them enjoy gnawing on seaweed on rocks.


Is it possible for clove polyps to be hardy?

Clove polyps are a resilient, soft coral, making them one of the easiest-to-keep corals and an excellent choice for beginners.

They’ve also been known to grow extremely quickly, almost like intrusive coral.

Why isn’t my Duncan Coral opening?

It is normal for one of these corals to stay closed for a few days after being introduced to the tank because it needs to adjust to its new surroundings.

Is the expansion of clove polyps feasible?

While both xenia and GSP are easily spread, you can contain or cull them, but the cloves simply release adenomas and expand all over.


Thanks a lot for tagging with me till the very end. I hope now you understand why clove polyps are not opening. 

You should find the reason properly before finding the solution. It won’t be so hard for you to maintain clove polyps.
