Nanochromis transvestitus
West African Dwarf Cichlid
虹彩短鲷
Nanochromis transvestitus is a delightful dwarf cichlid from West Africa. First discovered in Lake Mai-ndombe in 1973, it has been a favorite for specialized hobbiests since then. For many cichlid species the males are much more colorful than females. However, with Nanochromis transvestitus this is directly opposite as females are much more colorful than males. In recognition of this reversed coloration the authors of the scientific description provided the name transvestitus.
 Dominate males are extremely aggressive and will viciously attack other males and non-receptive females. Pair bonds only seem to last part of the time and it is not uncommon to have a normally agreeable pair suddenly at war. You must have many hiding places if you want to keep these fish.

Breeding Nanochromis transvestitus is generally a challenge. It is best to start with a small group of fish of mixed sexes. 5 - 8 fish make a nice start. Put them into a densely planted tank with many caves. Feed them well any you will likely find that a pair will form. At this point you have the best results if you can remove most of the other transvestitus from the tank. I always try to leave the pair as I have had pair bonds shattered when moving them. 
Nanochromis transvestitus have very obvious mating rituals. Here a female is bending her body to emphasize her swollen abdomen. Despite her "full" look and slightly extended ovipositor, this female will probably not breed for at least another week as she continues to ripen produce additional ripe eggs. Transvestitus are very demanding for successful spawning. You will need water with almost no hardness and a pH of about 5.0. If you cannot meet these conditions the fish might spawn but it is very unlikely that the eggs will hatch. 
Nanochromis transvestitus eggs will hatch in about 5 days and the larval fry will need another week or so to become free swimming. They will take baby brine shrimp or microworms immediately. They grow fairly quickly with lots of live food and plenty of high quality water changes. Young transvestitus are easy to sex as the distinctive caudal (tail) fin patterns are easy to pick out.


虹彩虹彩短鲷,学名:Nanochromis Transvestitus 英文名:Transvestite Cichlid。是西非短鲷的一种,1973年首次发现于Mai-ndombe 湖,从那时起就在西方流行。体长大约7cm,公鱼比母鱼略大。一般雄性的鱼会比雌性漂亮,但是虹彩短鲷的雌性有比雄性更加丰富的色彩。 
   
   虹彩短鲷比较难在鱼缸中饲养,占主导地位的雄性会猛烈的攻击其它雄性和它不喜欢的雌性。最终配对的一对亲鱼一般是在一大群成年虹彩短鲷打架之后,它们才会选择性的配对,而且就算是配对好的亲鱼,突然再次开战也是很常见的事情。尽管有人已经将多条鱼放在一起养,也无法避免它们激烈的战争。最好是在鱼缸中多放一些隐蔽物,以供他们藏身。但是多条饲养下很难看到产卵的场面。 
   繁殖虹彩短鲷是一个不小的挑战。最好先从混和饲养5~8条鱼开始。放在一个有密集植物和隐蔽无的鱼缸中。当你发现其中有一对鱼配对成功的时候,就将其他的鱼捞出,留亲鱼在原缸中。虹彩短鲷的产卵要求在西非短鲷中比较高。它们需要几乎没有硬度的软水而且ph值约为5.0。如果你不能满足这样的要求,亲鱼可能会产卵,但是极可能不能孵化出幼苗。
   虹彩短鲷的孵化期为5天,幼鱼会聚集在一起游泳一星期左右,之后便会分散开来。刚孵化时可饲喂刚孵化的丰年虾。幼鱼期生长迅速,但是也要保持水质的稳定。
