I also would like to thank for the sufficient informations!
But – to come back to one of the first posts here in this thread – as I remember the question was not:
Which plants can be used in a paro aquarium AND come from the original habitats of Parosphromenus –
but: Which plants can principally be used in a paro tank, which plants can stand the water conditions – no matter were they come from. In general – not confined to the habitats of paros.
