Something tells me this isn't just cute behavior. Why do my two goldies kiss on the lips several times a day? It's a 'quick' kiss then they move on but they do it several times a day. They're about 6 inches each in a 90 alone. They've got a good amount of java fern on driftwood. They know how to tear up on some duckweed, but I have a free supply of that from my friend. My main question is this, why the kissing?
