The mandarins and scooters in the genus同步性are among some of the most endearing and staple favourites in the aquarium hobby. Mandarins are especially colourful, and their crawling like behaviour coupled with their unorthodox appearance makes for some of the dare we say, cutest, fish out there. Although famed for their difficulty and reluctance to feed, the dragonets in recent years have seen promising ventures such as successful圈养繁殖efforts byORA, 和S. picturatus平均每批生存率平均达到90-98%。
在四种“普通话”中同步性genus, onlyS. Splendidus和S. picturatus很容易获得。西方人司法部from Western Australia is extremely rare and expensive, and after making a brief appearance awhile ago has vanished again without so much of a trace. The other “mandarin” is圆环圆环, and likeS. occidentalis,在交易中很少遇到。尽管可以在菲律宾找到它们,但它们的神秘和静音的色彩及其不确定的范围可保护它们免受许多收藏的影响。S. cigneris他的容貌也是独一无二的,looking like an intermediate between a mandarin and a scooter.
Photos and information ofS. cignerisare scarce, and the few pictures out there are taken by dedicated Japanese divers. Very interestingly though, these few images showS. cigneris与S. Splendidusover coral heads in Anilao, Philippines. We consulted with Dustin Dorton of ORA with regards to interspecific hybrids of同步性。根据达斯汀的说法,他们已经S. Splendidusspawning withS. picturatus, but the eggs were non-viable and development stopped after the fourth cell division.
基于S. SplendidusxS. picturatus, it is highly possible thatS. SplendidusxS. cigneris也会导致无菌卵。据我们所知,还没有记录过任何杂种普通话。尽管与这两个物种相吻合,但似乎它们是故意一起产卵的。有许多这样的照片,似乎并不是偶然发生的一张照片。
It is not uncommon for interspecific hybridisation to occur. However in such cases, one species would usually have to be very rare, and the difficulty in finding a mate of the same species would drive it to spawn with another in a similar complex. There are many examples, and a well known one involvesCentropyge ferrugata和C. Loricula在菲律宾。在那个位置,C. Loriculais very rare while the closely relatedC. Ferrugata丰富。这力量C. Loricula与C. Ferrugatain the event where finding a similar mate is difficult.Centropyge multicolour在菲律宾,面临同样的问题,并已知与C. Ferrugataas well asC. bispinosa在那个区域。
We don’t know the abundance ofS. cigneris和S. Splendidus在其重叠范围内,但根据照片和视频,似乎两种物种都不是罕见的,也不是很少的,无法经常进行种间配对。在上面的照片中,同一物种的两个性别之间的常规产卵重音(S. cigneris)发生在头顶上方Porites。许多产卵对的患病率应表明大致健康且丰富的人群。
It seems therefore strange why two species that are neither rare nor viable would intentionally come together during spawning rituals. In the *third photo above you see that a pair ofS. cignerisin spawning accent is interrupted by an intrudingS. Splendidusresulting in a threesome of sorts.
有趣的是,似乎有两种颜色的形式S. cigneris。一种更暗淡的褐色形式,另一种更红色的色调。S. Splendidus也以两种颜色形式出现,一种红色和蓝色形式。来自Ora的Dustin与我们分享了,成对的红色X红色普通话,由此产生的后代都包含红色婴儿,而成对的蓝色X蓝色将导致后代为100%的蓝色婴儿组成。有趣的是,红色X蓝色或蓝色X红对产生相同的“混合”后代,并具有两种颜色形式的特征。尽管有些可能很难与普通的蓝色普通话区分开,但有些人在原本蓝色的骨盆鳍上出现了明显的红色条纹。
Due to the lack of photographic documentation and lack of breeding evidence inS. cigneris,尚不清楚两种颜色形式是繁殖,还是首先是不同的颜色形式。我们所知道的是,尽管有足够的伴侣可供选择,但这两个物种经常没有看到在一起产卵。由于缺乏证据表明成功穿越,以及Ora的经验S. SplendidusxS. picturatus, it is likely that hybrids are not viable.
无论如何,仅考虑大自然的许多幻想想法,这是很好的。下面的视频显示了一对S. Splendidus还有一对S. cigneris,同时产卵。在13秒的标记中,两对物种都在同一时间的同一时间上升。现在这很酷,即使没有种间间的汉基品粉也涉及。
