It was suggested I buy these and I think they are definitely good bets:
it's just from who. I kind of just want to get it done. I have a small space of time coming up to set up new tanks.
As for plants here are some to consider:
Java Fern (low light, medium grower)
Java Moss (low light, fast growing)
Anubias (low light, medium grower)
Common Crypts (low-med. light, medium grower)
Anacharis (low light, extremely fast growing)
Hornwort (low light, fast growing)
Moneywort (low light, med-fast growth)
Pennywort (medium light, med-fast growth)
Water Sprite (low light, fast growth)
Water wisteria (low light, fast growth)
So of these plants I highly suggest floating water sprite for any Betta's, especially a sorority since they will spend lots of time up at the top, it breaks up their views of each other and helps block when chasing begins. They also sleep in it.
Hornwort and Anacharis are sometimes finicky but both can be floated or planted. Anacharis is generally a cold water plant but can be acclimated to higher temps like 80*. Grows like a weed too.
So for amounts of plants, I would suggest getting plenty that will grow tall like Anacharis, Hornwort, Water wisteria and water sprite. And then put some Java Ferns and Anubias between them so you're blocking most area's for the girls. You might also be able to get away with Amazon swords which are great for sororites because the leaves get so big and they grow tall. And with an NPT they should do just fine because they are heavy root feeders.
I also recommend Green Temple (Hygrophilia corymbosa), grows pretty fast after it gets established the plants get big and it's easy to just snip and replant when it gets tall. The girls love it and lay on it a lot. It is also a very big nitrate sucker upper. It's probably my favorite plant in my sorority right now because the leaves are so big and pretty.
We have been trading and getting plants from the planted tank for free or the cost of shipping in ROAKS or just by the kindness of the members, I have ordered some specific rare plants off of members as well, I am liking that forum better that the plant sites, better selection and better prices and they tend to throw in a lot of extras
