crossbreed yellow and sailfin tangs?

Hey everyone,


I have a sailfin and yellow tang that seem to be "pairing." They swim with each other, and rub their tails together similar to the youtube video: http://www.youtube.com/watch?v=W8klQ6Imuxk


A few of the comments on the youtube video state that they're fighting, but I definitely don't think that mine are fighting. They certainly don't chase each other around the tank, and they get along great.


Just curious if this can be a mating ritual that tangs do since it's been a "full moon" lately. I've read that tangs usually spawn around full moon, and it happens very rarely in captivity.


This thought came when I noticed my sailfin tang not acting "normal." When I got home from work, I noticed that it had found an area in a rock formation and was just sitting there. Now since I've fed the fish, it's come out of its "hiding spot" and is acting more normal.


And any ideas on why the sailfin might do this? It doesn't have a disease, and hasn't really changed in appearance other than the purple spot right before its tail is more distinct then it has been.


Anyone know if yellow and sailfin tangs are capable of spawning?


Any input would be greatly appreciated! /DesktopModules/ActiveForums/themes/_default/emoticons/biggrin.gif

 

I figured it wasn't spawning but I didn't really know what it could be. I wish I could post a video to GIRS to show you the current situation. My yellow tang (which is smaller) will approach the sailfin (which is much larger) and initiate the behavior.
I've never seen the two chase each other around the tank, nip at fins, nor swim quickly into one another. Even during feeding, they seem to share the "algae clip," taking turns eating while neither nudges the other one nor fights for the food. So, i guess the yellow tang is just seeing if it's larger than the other? No matter how "aggressive" it may be, I don't see them harming each other by any means.

Thanks Jazzy!
