As we often discuss here atSaltwater Smarts, one of the frustrating aspects of the marine aquarium hobby is the fact that some of the species commonly or occasionally available in the trade have no business in the average hobbyist’s aquarium. Some of these species grow way too large for virtually any home aquarium, some have a highly specialized diet that is impractical or impossible to replicate in captivity, and some are just too sensitive to endure the rigors of capture, prolonged shipping, and repeated acclimation to different systems.
但是,我们还需要将其添加到该列表的列表中,这些物种(无论是故意还是无意识地)作为热带物种并将其出售给不怀疑的业余爱好者。
Here’s a sampling of the species you might come across that can be maintained in cool-water marine systems but won’t last long in the average tropical aquarium:
The Catalina goby
With its stunning reddish-orange coloration and electric-blue stripes, the Catalina, or bluebanded, goby (Lythrypnus dalli) is a real eyecatcher. Couple its good looks with its diminutive size and peaceful disposition, and you’ve got an ideal reef tank resident, right? Not so much, unfortunately.
L. Dallihails from the Eastern Pacific (from the Gulf of California to Equador and north to Peru according to FishBase) and thrives in waters ranging in temperature from the mid 60s to low 70s Fahrenheit. At typical tropical marine aquarium temperatures, this cute little goby is virtually assured a severely limited lifespan.
The bluespotted jawfish
bAnother Gulf of California resident, the aptly named bluespotted jawfish (Opistognathus Rosenblatti) appears in the hobby somewhat infrequently—and usually with a rather dauntingly high price tag to boot. If you should come across one of these beautiful, blue-spotted burrowers and feel tempted to buy it, keep in mind that unless you have a cool-water system, you’ll likely end up spending a lot of money for a specimen that you won’t have the opportunity to enjoy for long.
The good news is, there are several jawfish species on the market that are truly tropical and sold at a reasonable price—including my personal favorite, the黄头, or pearly, jawfish (Opistognathus aurifrons).
卡塔琳娜清洁工虾
Moving into the realm of cool-water motile invertebrates, we come to an Eastern Pacific shrimp species—the Catalina cleaner shrimp (lysmatacalifornica), a.k.a. the peppermint shrimp. Like the aforementioned fishes, this shrimp is looking at a significantly shortened lifespan if kept in a tropical aquarium.
将通用名称“ Peppermint Shrimp”应用于这种凉爽的甲壳类动物可能会引起极大的困惑lysmatagenus,L. Wurdemanni, are also known by this common name. However, being a Caribbean species,L. Wurdemanni对于热带水族馆来说是一个更好的选择。
玛格丽塔蜗牛
所谓的玛格丽塔酒或玛格丽特蜗牛(Tegula funebralis)通常出售给不知情的业余爱好者,作为礁石清理人员包裹的一部分,以控制藻类。las,这个东部太平洋蜗牛在这样的组合中没有任何业务,因为在热带温度下保持短时间后会灭亡,这是悲惨的,因为该物种在本质上具有很长的寿命。
I should point out that the common name “margarita snail” is also applied to various members of theMargarites属,例如M. pupillus。但是,这些也是非热带蜗牛,如果在热带温度下保持不长。
