Okay, I did it...the girls were on sale at petco, and I got five. I've read the sorority sticky, and I've got tons of silk plants and lots of hiding places for them...it's just a matter of getting everyone quarantined so that they can go into the big tank when they're ready. :)
Now, my question, I've got a 10g, a 20g, and a 30g. With five females, most about mid-sized, which tank should they go into? They've got a 20-30g filter ready for them (being running it in an established tank, so it's ready for the cycle to start) so filtration is not an issue, and I've got appropriately sized heaters as well.
Also, I believe I've got enough leftover silk plants that I can densely cover any of the sizes with no trouble.
I read on the sticky that it was actually better to overpopulate a tank with females because it lead to less bickering and in-fighting...and I know the general rule of thumb is 1 inch of fish to each gallon of water...so the ten is technically plenty big enough for them, but would they possibly be happier in something a little bigger?
I've never done this before, so I'll leave off and listen to the experts! :)
