Explanation of the symbols


Family : Serrasalmidae
Origin : Amazon river
Length : > 30 cm - 12"
Min.length aquarium : 300 cm - 120"
English name : Pacu
Peaceful, large schooling fish, only suited for a very large aquarium because he needs a lot of free swimming space.  When the aquarium is to small they become shy.  The aquarium should be set up with roots and driftwood because they need hiding places.  Plants that are to soft are eaten so you better don't use them.  They don't care about the water quality. 

You should give them mainly vegetable food like spinach and lettuce.  Fruit is eaten as well.

Captive breeding has not been achieved.
