Neon Dwarf Gourami-Male

[sebass]

My male is making a bubble nest but it's the only gourami and there are no other females in the tank

I also tested the parameters and everything is perfect

Gouramis and Betta males will blow bubble nests regardless of having an available female around.

If you add some floating plants he'll like it even more.
