The last couple of days, my clownfish (which are still in the 14gal) are doing that vibration dance where they vibrate really quickly while swimming on their side to show to the other they are becoming submissive. They are already paired up (haven't mated yet) and have been doing this a bit for a while but just about an hour each day. They do it for a minute or two, and take a break, then start again. I know they are already "together" because they share territory, the smaller one swims after the bigger one, they NEVER and I really mean NEVER, have fought in my aquarium, and they sleep together EVERY SINGLE NIGHT in the anthelia that Lyn gave me (BTW Lyn, it is still doing great and the clowns love it. Thanks again! ). Also, it isn't just the male that is vibrating to the female, the female is vibrating back and doesn't get aggressive the slightest bit. I have NEVER seen them bit/nip/chase/attack the other. I'm not worried about them pairing up because they already had when I bought them. They have never been sick or gotten Ich, but I'm just wondering if they are doing this as Pre-Spawning, or if they are doing something else? I'm watching them as I type this, and they just seem to be trying to "show off" to the other. Anybody got any ideas on what they are doing?
