Pairing GSMs...wish me luck!

Originally I was going to get a pair of bicinctus for my new 50 cube, but the shipping costs from the seller priced them out of my reach. I was disappointed, but as luck would have it, I came across two very beautiful "second-hand" GSMs this week: a female, about 3" long, that was traded in at a friend's coral farm; and a juvenile, about 1.5" long, that was traded in at my LFS. Since GSMs were the other species I'd been considering (and the female was only $10), I was very happy.

With the assistance of my LFS, I'm gambling on trying to pair them up. I brought the female in to my LFS (at their suggestion) today, and after acclimating her, they dropped her in the tank the juvenile was occupying. At first they didn't even seem to notice each other, but when they did, the juvenile quickly vacated the BTA he'd been occupying, then came back a moment later to face off with the female.

They spun in a circle for maybe 10 or 15 seconds (no biting) before the juvenile fled. He hung out at the top of the tank for a few minutes, then hid in a cave right under where the female was located. I watched them for about half an hour, during which time the female would periodically seek out the juvenile in his hiding place. They drew up alongside each other and kind of circled each other; finally, after about the third time, the juvenile did the submission-quiver. They never attacked each other and there was no jaw-locking or biting.

By the time I left (the store was closing) the female was still dividing her time between the BTA on top of the rock structure and visits to the juvenile below it. You could tell they were still wary of each other, but I didn't witness any aggression. I'm cautiously optimistic that they'll turn out to be compatible. The LFS owner said that 24 hours should be long enough to tell whether or not they're going to get along, so...here's hoping I get to bring them both home tomorrow!
 
24 hours should give you a good clue if they will tolerate each other. My huge GSM (like 4.5") killed the first juvenile I introduced. I even had an eggcrate box for the juvenile to hide in. I woke up the next morning and found him. The second juvenile I introduced was the same size as the first juvenile. She took to the second one fine and they never fought at all.

Good luck! GSMs are beautiful fish.

Yikes! Poor little guy! :( Did you see signs of aggression from the beginning, or did it come as a complete surprise? I'm glad she accepted the next one--do you still have them?

I hope mine isn't going to slaughter her prospective mate--I'd feel terrible. The people who traded her to my friend for a bonded pair (they're trying to breed GSMs) had apparently tried to pair her with another juvenile that was slightly larger than this one, and all they did was fight. She still has a healing pectoral fin from that attempt. The way she and the smaller juvenile were interacting last night makes me hopeful...but cautiously so.

They really are spectacular fish, even if they do have the social skills of pirate captains. :lol: I even like their ferocious nature (as long as these two don't turn it on each other). The female I just got has light blue lines outlining her bands, and her color is still bright red even though she's got some size on her. I have this RBTA being held for me by another RC member until my tank is stable enough--it finished cycling a few months ago. I think the combination will be gorgeous. I can't wait.
 
I introduced the first juvenile (it was just over an inch long) in the early afternoon on a Saturday. They were fine together, and I saw no aggression, even at feeding time. I woke up the next morning and it was dead with torn up fins. I'm guessing that she didn't like him sleeping near her, and he couldn't find the eggcrate to sleep in.

I have them now, and they have been together for a little over a month. My plan is to breed them too. Hopefully he grows fast and they start breeding. :D
 
Checked in on the GSMs this morning on my way to run errands...no bloodshed overnight. I brought them home about an hour ago and acclimated them together in a large specimen container for about 45 minutes. I just released them. They stay fairly close to each other and seem quite calm. They're just hovering and looking at their new surroundings. So far, so good!

Me too. Good luck! :D
