o.o Okay...I had a whole thing typed up for ya....looks like I'll have to change it now. :/ Oh boy...
Alright, first off, remove ALL your females ASAP and put them back in their cups until you decide exactly what you want to do; you are not prepared or experienced enough to start a Sorority. While its true SOMETIMES
females can be kept in groups in a well planted 10+ gallon with lots of hiding places
, this should only be attempted by a more experienced and well prepared keeper, because even in the perfect conditions its risky and doesn't always work out.
You have a couple of options now:
-Keep 2-3 females and keep them in the 10 gallon divided
, each in their own little section.
-Keep one female and return the rest and have a little community with a single female and a coupe other peaceful fish.
Take back the BN and the Barbs regardless. Both species will outgrow a 10 gallon rather quickly, and Barbs are not only schooling fish(need groups of 5 or more)but they are far too aggressive to be kept with bettas.
While it may look like everyone is doing okay now, things can change in the drop of a hat. Literally
. And I can promise that you will have problems, likely in the near future, resulting in sickness(since you are quite over-stocked...not to mention adding that many fish at once will cause such a bad ammonia spike that I wouldn't be surprised if it wiped out your whole tank in a few days)and likely more death, which I'm sure you don't want.
So....you are going to have to take back quite a few fish. Hopefully the store will give you some credit, which you can use to buy a few other necessities for your new tank.
And now that we have the most pressing issues out of the way.....time to focus on the wonderful topic of the Nitrogen Cycle.
I'm not the best at describing the entire process(at least through text) but this explains the it all fairly well, in my opinion: http://www.fishlore.com/NitrogenCycle.htm
I'll see if I can dig up a little more on a fish-in cycle for you, unless you'd rather do some more research on your own.
ALSO, somethings you'll want to go pick up(if you don't already have them):
water testing kit(the strips aren't accurate, stay away from them), API brand is the most popular one I see and it works quite well. This is essential
to have, not just for the cycling process, but for in the future. You think something might be off/a fish acting funny? You've got your kit right there to test and eliminate the possibility of water quality issue. You'll also need it in order to test during your cycle so you know when to make water changes.
-A Gravel siphon. Though you don't want to disturb your gravel until your cycle is completed and stable.....this is a very useful tool for water changes, both during and especially after your cycle. It'll make water changes go much quicker and easier.
Lets see....thats all I can think of for now. I wish you the best of luck with your new bettas and, as always, if you have any questions or concerns, please feel free to ask me or anyone on the forum. We're always ready to help :)
