NPS是你见过的独一无二的珊瑚,它们大多奇形怪状,举止神秘莫测,,它们还有另一个名字,无虫黄藻珊瑚,意思是这类珊瑚未含有虫黄藻。不过,研究发现,我们所想的许多无虫黄藻珊瑚其实是含有共生藻的。

 

NPS家族庞大,包括软珊瑚类(海柳,海鳃,和一些软体)和石珊瑚类(一些LPS),一些无脊椎动物与NPS的饲养方式一样,比如海百合,海绵,火焰贝,海鞘等等。


 

由于这些珊瑚无法进行光合作用,它们需要进食来获取能量,这是一个大问题,因为这些珊瑚必须保证良好的水质,同时需要不断的进食。

 

你需要喂什么食物?喂食频率是多少?你需要喂食各种各样的食物,最小至各种浮游植物到小轮虫,大至桡足类,糠虾等等,显然,有大口器的珊瑚需要大个体食物,反之亦然。

 

这类珊瑚每天需要喂食好几次,喂食多少根据你鱼缸大小和过滤器处理量来决定。一个聪明的方法是根据你的喂食方案,找到一个现有的类似于你的NPS缸,模拟它的喂养时间表,并根据你的珊瑚的反应调整你的喂食方案。

 

自动喂食器非常受NPS缸饲养者的欢迎,它可以省去手工喂养的麻烦。这些喂食器通常是自己动手做的,包括让你的喂食管通过冰箱来保持食物的低温。你可以在当地的鱼店买到自动喂鱼器来添加干粮。


 

在野外,许多珊瑚,比如太阳花珊瑚,白天通常都是不开的。在珊瑚缸里,你可以通过喂食来训练它们,使得你在开灯时期也能欣赏到它们的身姿。

 

一些无光合作用珊瑚,比如侧孔珊瑚类需要黑暗环境,他们的组织容易受到生在在其身上的其他生物的影响。根据我的经验,饲养一缸纯NPS珊瑚比混养一缸各种珊瑚容易得多。你可以不用考虑其他珊瑚,为NPS专门定制适合的灯光。



NPS珊瑚所需水流同SPS缸一致,NPS需要水流来捕捉食物,为了使水流更具有效率,他们的水螅体可以操控周围的海水。

 

此外,你还需要有一个强大的过滤系统,NPS的饲养者经常使用藻缸,UV灯,生化球或者其他介质,这些都是除了蛋分,活性炭,换水之外常被使用的。

 

饲养一缸NPS缸需要精心照料,这绝对值得你这么做,因为NPS如此神秘莫测,我们需要更好的了解它们。


原文:

Non photosynthetic corals (NPS) are some of the most unique corals you will ever see. They have the most odd shapes, textures, and cryptic behaviors. Their other name, azooxanthelle, suggests that their zooxanthelle is absent. However, studies have found that many of what we thought were azooxanthelle corals do contain some symbiotic algae.

 

NPS corals include of many different types of corals such as soft corals of Alcyonacea (gorgonians, sea pens, and soft corals) and Scleractinia (LPS corals). There are also several invertebrates that have the same care as NPS corals for example crinoids, sponges, flame scallops, and tunicates.

 

Because these corals do not photosynthesize, they need to receive their energy from food. This can be problematic because the corals need to have good water quality while also consuming food constantly.

 

So what type of foods do you feed and how often? You will want to feed a mixture of food with a range of particle sizes, ranging from tiny phytoplankton to small rotifers and larger calanus copepods & mysis shrimp. Obviously the corals with big mouths want the big food and vice versa.

 

The corals should be fed every day a few times a day. The amount of food you feed depends on the size of your tank and filtration. A clever way to base your feeding regimen would be to find an existing NPS tank similar to yours, mimic its feeding schedule, and adjust your feedings based on your corals’ response.

 

Automatic feeders are very popular with NPS tanks. It takes out a considerable amount of the manual labor. These feeders are usually DIY and involve running your plumbing through a refrigerator to keep the food cold. Dry foods can be added with an automatic feeder that is available at your local fish store.

 

In the wild many corals like Tubastrea are closed during the day; in your tank you are able to enjoy them at all times once we train them by feeding them when the lights are on. Some azoox corals like Dendronepthya are found right on top the reef standing next to Acropora.

 

Other non- photosynthetic corals, including Distichopora, require darkness; their tissue is susceptible to other organisms growing on them. In my experience, it is much easier to have a non- photosynthetic tank than NPS corals in a mixed reef. You can manipulate the light without it costing other corals.

 

NPS corals need just as much current as you would put on your SPS tank. They rely on water movement to capture their food; their polyps’ position can manipulate the water around them in order to make the current most effective.

 

Additionally, you need a superior filtration system. Non- photosynthetic reefers have used refugiums, UV sterilizers, biopellets, and other media. These are used in addition to your standard skimmer, carbon, and water changes.

 

Non- photosynthetic corals require love, care, and tedious work. It is well worth it because they are mysterious and we need to have a better understanding of them.
