I'll say this up front..I'm not a fan of dwarf gourami's at all.. many have health issues that may be related to the line breeding of the fish.
That said.. i have successfully bred apisto's, bolivian rams, angel fish and a few other species.
I have been trying to breed blue rams with zero success. I 've kept a mulitude of species that are considered 'hard' to keep. Including Altum, discus(both wild and domestic) wild apistos and wild pleco's.. all with good success.. the most difficult fish for me to keep....Ramirezi...hands down.. after years I've finally found several including 1 breeding pair(no babies yet)..eggs every month but they go bad...
that said.. Blue ram pairs are very social and beautiful fish.(why I keep trying)
if you have any tetras in the tank.. you won't need to worry about babies as they will get eaten..
if you do have success breeding you can simple remove fry to a growout tank..
