pomacanthus navarchus。pomacanthus xanthometopon。这些是我最喜欢的几件事。但是,巴厘岛到底发生了什么?除了闷烧的火山(隆格山)在这个岛上的天堂里散发出灰烬和诱捕不幸的游客,Bali Aquarichhas yet again succeeded in captive breeding yet another angelfish species. Not one, but two; from two different genera.
By now it is becoming increasingly difficult to keep up with Bali Aquarich’s proliferation in the angelfish captive breeding scene. Their numerous accolades plaster this blog like ribbons at an Ohio pony fair, and we (literally) find ourselves back in Bali every two months to cover something new. If you could see my passport over the last year, it looks like a sticker book with a skewed preference for Bali visas.
Let’s start with the newPomacanthus.在此新产品之前,巴厘岛Aquarichdabbling in this genus with their perennial staple,P. annularis。快进一点新混合动力involvingP. imperatorwas produced when the two parental broodstock were mixed in the same containment unit. Not long after (we’re talking literally in the timespan of a few months), yet anotherPomacanthus婴儿已经生产了,但是这次是从子属中产生的Euxiphipops。
Euxiphipopsis a small subgenera consisting of three species. They areP. Xanthometopon,P. navarchus和the “ugly duck”P. Sextriatus。The three species are known to hybridize amongst themselves wherever their ranges overlap in the wild. None of them have been captive bred before, until now.
巴厘岛的最新Pomacanthus提供该子属的一名成员。最大的问题是,哪一个?这些约50天大的少年是从一个容纳一对繁殖的封闭装置中长大的P. Xanthometopon和P. navarchus。While the juvenile coloration of both species are distinctive enough at about 1.5 – 2 inches, they are nearly impossible to diagnose when they’re the size of a thumbnail. But because the broodstock unit has two angelfish of the same subgenera, there are three possibilities to the identity of this fish.
The first two possibilities is that this fish turns out to be pure bloodedP. Xanthometopon或者P. navarchus。Based on the white barring, i’m inclined to think thatP. Xanthometopon是一个更有可能的情况。P. navarchus幼年形式的蓝线非常薄,并在其发育阶段非常早就发展成人色彩。但是,如前所述,这些仅是缩略图的大小,在此阶段,所有诊断特征几乎没有用。来自巴厘岛Aqurich的Su先生认为这些可能是P. navarchusinstead, based on the slow growth rate associated with this species. Indeed, these are very slow growing, and are only half the size ofHolacanthus clarionensisat the same developmental stage.
The third possibility is that this new baby could be of hybrid origin. With both parental broodstock housed in the same vat, it is not entirely implausible that accidental hybridization, or incidental, in the case withEuxiphipops,可能发生。同样,在这种大小上,现在说得还为时过早。
除了将这种新产品缩小到子基因级别以三种可能的情况之外,我们对任何事情都不了解,直到他们长大了。无论如何,这仍然是一个行业,并与Su先生及其公司在水产养殖场景中做得很好的庆祝活动(再次)表示祝贺!
This is the 7th angelfish species that Bali Aquarich has succeeded in rearing. We mentioned at the start of this article that this is just one of two new angels, so keep reading for the revelation of the 8th species.
