Top swimming

[carolines100]

Hi all my delhezi as decided he likes to swim on top with my 2foot arrow which the del is 12inch so prob end up as dinner if he carries on as the silver gets very aggro from time to time . I have 3 rays on bottom but have lots off hide outs for the delhezi . He's been doing this for over a week now any ideas on why he's decided to do this ??

In nature:
To understand how this behavior helps young polypterus survive, it helps to know about their natural habitat. Bichirs come from lakes and river systems in Africa, some with quick moving water and all with plenty of vegetation along the banks.

This vegetation acts as a nursery for young bichirs, who remain where the water is calm, and hide amongst the leaves. Because bichirs need to breathe atmospheric air, baby bichirs and ropes cannot afford to venture too deep, and must remain relatively close to the surface. By floating, they have easy access to breathe air, easy prey such as insects and their larvae, and remain relatively sheltered from predators.
