Some ideas for Corydoras biotopes

Have been looking at Youtube for some really good videos, here's a collation:

Scleromystax sp. (barbatus?) in Rio Quiriri - 15 deg C

 

Swarm of corydoras in Manaus, Brazil



School of wild Corydoras sp."NOVO AIRAO" in the Rio Negro, Brazil

School of wild Corydoras melanistius in the stream of Amazon

Corydoras robineae - Upper  Negro River

Corydoras cf. narcissus in  Cano de La Libertad, Colombia (I don't think it's C. cf arcuatus)
