Eh? Where did you hear that? My rainbows, unless I'm not in the room or they are not playing in the filter outflow, are always at the front watching me.redtail11 said:They may not be scientifically as active, but they have twice the vertical body mass and tend to swim near the glass, so they appear more present.
As for body mass, unless you are referring to giant gouramis, I've never seen a gourami with the body mass of an adult Boesemani. Please refer me to some site that lists how deep they get. I'd like to compare them.
