Koi Fish 锦鲤 4"-9"

General Notes:
Although good community fish in the right setting a little care should be taken with this species. Keep a larger than normal group of these fish of at least eight individuals this eliminates fin nipping which can occur if to few are kept. Don't put temptation in their path, don't keep black line penguin tetras with guppies, Siamese fighters, angelfish or any other fish which has long or flowing fins. When in the right setting as outlined above black line penguin tetras are great community fish. They are lively with lots of interaction among their group and they are easy to care for as well as being very hardy.

Feeding :
Wild black line penguin tetras feed on worms, insects and crustaceans. Try to reflect this in their diet by offering lots of suitably sized live or frozen food such as blood worms, glass worms, daphnia, cyclops and brine shrimps. Using a good quality flake food with these will ensure a good balanced diet.

Sexing :
Adult females have a fuller and more rounded abdomen.

一般注意事项 :
虽然在适当的环境中使用良好的群落鱼类，但应该对这个物种采取一些措施。保持至少八个人的这些鱼比正常组更大，这消除了如果少数保持可能发生的鳍状物夹持。不要把诱惑放在他们的道路上，不要将黑线企鹅与孔雀鱼，暹罗战士，神仙鱼或任何其他长有或流鳍的鱼一起保留。如上所述，在正确的环境中，黑线企鹅是很好的社区鱼类。他们很活泼，他们的团队之间有很多互动，他们很容易照顾和非常耐心。

馈送 :
野生黑线企鹅以蠕虫，昆虫和甲壳类动物为食。尝试在他们的饮食中反映这一点，提供大量适当大小的活体或冷冻食品，如血虫，玻璃蠕虫，水蚤，独眼巨人和盐水虾。使用优质的片状食物可以确保均衡的饮食。

性别鉴定 :
成年女性腹部更饱满，更圆润。
