紫罗兰慈鲷
The rusty cichlid, Iodotropheus sprengerae, is a freshwater fish of the cichlid family. It is also known as lavender mbuna or lavender cichlid. This mbuna species is endemic to Boadzulu and Chinyankwazi Islands regions of Lake Malawi. It prefers a temperature range of 24-28°C.
Rusty cichlids are elongate fish that can grow up to about 11 cm. Juveniles and females are rusty brown color, while mature males have lavender purple hue.
Rusty cichlids are mouthbrooders. Females hold their fertilized eggs and fry, in their mouth for a few weeks before releasing the fry.
Although not entirely a peaceful fish, the rusty cichlid is considered one of the least aggressive among the mbuna cichlids. This quality makes rusty cichlids an ideal starter fish for aquarists with less experience keeping the mbuna. Hiding places and space should be provided or this fish will be bullied by their more aggressive tank mates. Rusty cichlids are omnivorous and will eat various kinds of food, but meaty food can often cause them serious digestive problems.

种属名称中词根“iodes”是希腊文中碘红色或铁红色的意思,紫罗兰的体色则是面部呈现铁锈色,而身体则显现深紫色,非常贴切。紫罗兰被认为是一个古老的品种,最初发现于马拉维湖的南部地区。原生环境中它们的栖息地范围十分的有限,只限于三个岛屿:Boadzulu,Chinyamwezi以及Chinyankwazi。它们是马拉维湖慈鲷出口的最早的品种之一
紫罗兰在幼年时期体侧有时会显现出向下延伸的竖条斑纹,成鱼后就不太明显了。紫罗兰无论雄雌,体色均为铁锈色,并散发出暗紫色光芒。雄性生长速度比较快,体形也比较大,通常具有比较多的卵斑和较长的臀鳍。这种铁锈色的体色往往容易使得它们和Labidochromis vellicans相混淆,区别是Labidochromis vellicans的头部形状比较突出,还是很容易区别的。
紫罗兰是一种相对温和的岩栖类慈鲷,不具有领地性,因此可以在一个较小的缸里饲养多条雄性成鱼。同种或同性鱼只之间偶尔会发生一些小规模的冲突,但极少导致相互之间的伤亡。这种温和的个性使得他们不适合与那些较大型的或更具有攻击性的鱼种混养,除非水族箱中有设有较多的庇护场所。
紫罗兰一种杂食性的慈鲷,它们啃食附着在或是栖息于礁岩上的各种小型动植物。繁殖容易,一旦成熟,它们就可以持续稳定地进行繁殖。每次产卵量在5至50之间。
