[Peter Finke]

I gladly confirm Helene’s message. Transporting eggs or even larvae to another cave has been witnessed by several people concerning several species. Rather often it is to be seen with P. ornaticauda and P. parvulus, but with other species, too. Helene is right in presuming that the presence of several caves adds to the probability of eggs being transported from the one to the other. This is no odd behaviour at all. Mostly, we breed Paros in small tanks with one cave only. But in nature, roots, leaves of submerse or emerse plants, wooden leftovers of different origins normally form a variety of natural caves, and enimies in the water and the air are abundant. So males seeking security for their offspring are quite normal a thing.
