I went to my local store and I got some Neon Blue Dwarf Gouramis like a month ago, one male and one female. The male is swimming with the tetras I have, but the female hides in the Java Moss. I have never seen her eat and she comes out rarely. Could the male be harassing the female? Should I put more females in there or are they okay? I heard floating plants could help, if so what types?
