Well the subject says it all. I have a 4" pink kisser in my 90 gal that likes to "perch" on things. Kind of like a loach would rest on the bottom of the tank, he perches on top of pieces of driftwood or even on the bottom of the tank. His dorsal spikes aren't up, so he's not stressed, and my ammonia and nitrite read 0. Is he acting normal? Anyone else have a gourami do this?
