60Ltr Square Tank

[TigerOscar11]

Hey guys,
Getting a decent aquaone 60ltr square tank off a friend and was wondering what dencent-ish sized fish i could put in as a centrepiece but still have maybe some male guppies and a few tetras?

What are the dimensions? I feel like I recommend these all the time but they're so lovely..peacock gudgeons HERE is more info on them.

I imagine this is a Aquaone 40, which basically means 40cm square, 64 litres.
 
Guppies should be ok in this, not so sure about the tetras though, depending on the species perhaps.
 
Maybe Chilli Rasboras, CPD are possibilities.
