当您注意到某些事情不对劲时,您正在漫步经过海洋水族馆,请注意自己的业务。当您进入房间时,无处不在的[插入鱼的名称]总是直达坦克的前面。您可以扫描坦克的每一英寸,抬起一块活岩,甚至在水族馆周围搜索地板,但您仍然空着。好像鱼刚刚消失在稀薄的空气中。
What gives? Alien abduction? Chupacabra? Sasquatch? The Rapture? Actually, there are always perfectly simple explanations for such “mysterious” fish disappearances—and only rarely do they involve Sasquatch.
Here, in no particular order, are the most likely scenarios:
It’s in the rockwork
是的,我知道你已经撕裂youraquascaping,但是再看一下!Some fish—especially very slender or laterally compressed species—can fit into surprisingly small holes or crevices in rocks, and they aren’t necessarily going to bail just because you lift up the rock they’re hiding in. Heck, some hobbyists even find stowaway fish in newly purchased live rock!
我想起了一个火焰的缠身我曾经表现出如此消失的行为。经过广泛的搜索和头部刮擦后,我终于发现了藏在最薄的“口袋”中的那个可怕的东西 - 像衬衫上的乳房口袋一样,在岩石的底面。
It’s in the substrate
例如,对于一些鱼来说,这是完全自然的Halichoeresspp.), to bury themselves in the sand when they’re sleeping at night or want to escape danger. In fact, it’s not unusual for newly introduced wrasse species that are prone to burying themselves to remain out of sight in the基质for several days before finally venturing out in the open.
它跳了起来
跳鱼并不总是保留在最初撞到地板的精确地点。仍然很活跃的标本可以将它们的方式拖入各种不寻常的地方,有时距离水族馆很远。另外,家庭宠物(也许最终达到了他们的愿望)并没有超越/彻底消耗“意外”鱼类。
它是在污水中,储备,溢出…
当然,并不是所有的跳鱼都在地板上。通常,他们设法将自己倒入水族馆系统中的其他充满水的隔间中,例如水箱,refugium,或溢出室 - 这是好的,因为它们通常有很大的机会幸免于难。
它被吃掉了
在这种情况下,显而易见的嫌疑人将是任何更大的掠食性鱼,共享相同的水族馆,但罪魁祸首也可能是掠食性的甲壳类动物(例如,罐头披披披披氏犬或螃蟹),饮食脆弱的恒星(Ophiarachna rocrassata),甚至是少数已知的piscisile sessile无脊椎动物之一,例如大象耳朵Corallimorph(amplexidiscusfenestrafer) or one of various and sundry anemones.
Of course, the fish could also have simply died from other causes and been scavenged by the resident cleanup crew. In a well-established system with a healthy scavenger population, this can happen surprisingly rapidly.
