Here's some advice from meh. ^^;
All righty. So, at Petco, they keep the Bettas in small little cups? This is both a blessing, *and* a curse. In a way, it's bad for the Bettas to keep them in such small cups like that, but at least you don't have to worry (as you would have to if the Bettas already happen to be living together in a store) about a set-up hierarchy beforehand! ^^;
I just set up a sorority today.

Since I was moving around some fish, and my male Betta was going in the tank with the females along with some platies, I had to move the females beforehand. This was carried out by a *lot* of buckets. Mr. Wimpy Fish was in a bucket, both females were in separate buckets (EACH), and all the platies were together. ^^; I had taken out some ornaments beforehand, and, since I couldn't let them stay in the buckets for too long, I put them in the tank.

Later, when I went out to PetSmart (where I get all my female Bettas from, because they all live in small little cups there; read above), I put them back in the buckets, added the ornaments, and went. I got 5 beautifully gorgeous females there. ^^;
They couldn't see each other, so it was ideal. Also, the tank was a bit different. ^^; When I got home, I floated the cups (with the tops *OFF*, because they will sink if the tops are on), in the tank, and, after a little while (I had to do high-class creeping to get up the stairs, because it was my Mom's idea to get the females, but we've spent over $200 on tank stuff in the last *WEEK* alone....

; We got our new 55-gallon tank, thoughs, so that's why ^^;

But, yeah, we had to make sure that my Dad *DIDN'T* know about these new females.... ^^;

), I poured the females in, letting the water from the cup out into the tank water (blehs, it's fine; you wouldn't buy sick females, anyways, so there's nothing dangerous *in* the water of healthy females.... ^^;

), literally just *ONE AFTER THE OTHERS*. ^^; I also poured Queenie & Aqua out of their buckets in quick successions, and.... No issues! ^^;
Two females had been spazzing, glaring at each other and flaring from in their cups while they were floating in the tank's waters (for temperature equalization), so I released them just a bit earlier than I had *intended* to. ^^; They looked like they were going to fight, but thens, the dominant figures of Queenie & Aqua came in....
You'll do just fines! ^^; I did, after alls.

Luckily, my females never really fight. ^^; >
