在将鹰鱼保存在水族馆中时,最常见的劝告之一是避免将这些掠食者用鱼或甲壳类动物饲养到足以吞咽的情况下。对于大多数带有最大尺寸在3到5英寸之间的最大尺寸的鹰鱼物种,只有很小的坦克同龄人才真正面临风险。
值得注意的例外是雀巢鱼(paracirrhites forsteri), which can reach a rather prodigious size and has a mouth to match. You really have to take that warning seriously with this species! That said,P. forsteriis a hardy, easy-to-care-for hawk that makes a worthy aquarium candidate provided tankmates and housing are chosen judiciously.
身体特征
P. forsteri具有深沉的身体和高斑的眼睛,典型的鹰鱼。它的最大尺寸约为8½英寸。随着鱼的成熟和收集区域的变化,着色变化。我遇到的大多数标本当地的鱼类商店在身体的背侧半部表现出一条深带(红色,棕色或黑色),腹侧半颜色为黄色或白色。标本中一致的是该物种的通用名称的来源 - 红点雀斑脸上。
喂养
如上所述,P. forsteri是小鱼和甲壳类动物的捕食者。在囚禁中,它需要容易喂食,并将接受各种肉类食物,例如mysids;切碎的鱼,甲壳类或软体动物肉;和食肉动物的冷冻公式。
住房
A bottom-dwelling species that is usually found perched on rockwork or branching stony corals with the front of its body propped on its pectoral fins,P. forsteri不需要大量的开放游泳空间。对于一个单个标本,在75加仑附近的水箱就足以满足最低住房。但是,如果您打算与坦克友保持一致(必须是体面的大小以避免做饭),那么更大的坦克可能更合适。
兼容性
P. forsteriis an aggressive species that will harass tankmates that are similar in appearance and/or attempt to occupy the same niche in the aquarium, including conspecifics (with the possible exception of mated pairs in large tanks). Generally speaking, it should arrive late or last in the order of introduction. Suitable tankmates include similarly sized or larger species that swim in open water, such as larger tangs, rabbitfishes, angelfishes, or community-friendly triggers.
尽管该物种在技术上是礁石安全的,因为它不会在无脊椎动物上吃东西或bble,但这并不是我的第一选择。一个问题是,鹰鱼有倾向于栖息在珊瑚上的趋势,有时会一遍又一遍地落在同一标本上,这可能会成为一种主要的刺激物,并防止珊瑚完全扩张。该物种也是一个相当贪婪的饲养者和大量的废物农产品,这可能对水质有害。
