We didn’t see this new development coming back in December, but leave it to Dr. Matthew L. Wittenrich to recently第二个猜测物种识别on some of the juvenile captive-spawned angelfish they managed to rear in late 2011, as posted on the Rising Tide Blog. Why is Dr. Witt second guessing the identification of his captive bred marine angelfish?
It turns out there was more swimming around in the Columbus Zoo and Aquarium with the Koran Angelfish broodstock. And now, well, some of the captive-bred offspring reared by the team at University of Florida’s Tropical Aquaculture Lab just aren’t looking quite likePomacanthus semicirculatus，古兰经或半圆的绑住。事实证明，还有成人蓝色环裙角，pomacanthus annularis, residing in the tanks where spawning occurred and eggs were collected. Based on genetic testing, they know that they’ve rearedP.半圆形. However, just like when we held out hope that Todd Gardner had managed to rear bothLiopropoma rubreandL. Carmabi一镜头，现在维特里奇博士似乎很确信有一些P. Annularis在混音中。但是等一下。如果这些鸡蛋都是来自一个晚上的产卵活动，并且潜在的两个物种都在产卵，那就意味着甚至可能存在混合体P.半圆形XP. Annularis在这个混合的少年中！
信用到应得的信用，正是泰勒·阿尔布雷希特（Tyler Albrecht）评论了我对Facebook上涨潮的博客文章的重新发布，他暗示了我的态度，颜色上有很大的显着差异。他的观察？“我投票支持蓝戒指。没有尾标。”果然，我开始拿出Endoh的“裙角”书Scott Michael的“熟女书籍”，并且在每个物种的少年的尾鳍之间存在明确的差异。
pomacanthus annularis少年对白色尾鳍有清晰的至白色的尾鳍，尾巴很少延伸到尾巴上，至少在某些照片中，颜色似乎以“白色条纹”为“结束”。同时，少年P.半圆形have more of a “clear edged” tail, generally showing 50% or more covered in pigmentation, and that coloration ends with a black band. Try these Google Image searches forjuvenilepomacanthus annularisandjuvenilePomacanthus semicirculatus看看你想到什么。
Of course, the reality is that these captive bred angelfish are still quite small, far smaller than anything you’d see imported, so their coloration and patterning will continue to develop as they grow. Of course, if any of these juveniles are actually hybrids, that could only further make identification difficult as the juveniles could show intermediate traits of both parents. Guess Dr. Witt’s just going to have to raise up every last angelfish to maturity so he can figure out what he and his team really have!
So what do you think, here’s 6 photographs – which species are they? Do you think we’re looking at the simultaneous first rearing ofpomacanthus annularis此外P.半圆形？如果我们还发现混合物中的混合后代是什么意思 - 那肯定是first第二人造Pomacanthus Hybrid（第一个是Martin Moe的混合体P. arcuatusXparu）。我找不到任何狂野的混合记录P. Annularisin my quick research.
