I'm sure almost everyone here is aiming for some thing or another, be it a bigger tank, to set up a sorority, to find awesome males, etc. If you want, post your plans here :D
Personally, I only have a half plan at the moment. That would be to get money to set up my second tank as a well planted and cycled one, then either get really nice males from aquabid or start a sorority of rescue females. (yes, they'll be legit rescues gotten at either a discount or for free from LFS because they are so sick).
I have way too many plans. My first is to get another male for the other half of my divided tank. I'm aiming for a petco HM. I also want an aquabid HM male, for which I really want to get that 5 gallon hawkeye for and plant it. I'd love to set up a sorority. I also need to add a few more fish and a couple shrimp to my 10 gallon community with a betta. And I have eventual plans for a really big tank. Like 55 gallons and up.
But unfortunately, only getting another male for my divided tank and finishing my 10 gallon are options right now. I'm in college and in a temporary apartment and already have a 10 gallon, a 5 gallon, a 3 gallon and a 2 gallon tank.
I've acted on all of my plans so far. Sorority's all set up, the girls are getting along, and all 4 of my boys are healthy and happy.
At most I may end up upgrading my males' tanks this winter...(new plants, decor and whatnot)
I'm pretty sure I'm set with the amount of bettas I have now... but if on the offchance I come by a betta in need, I may take a rescue in at least temporarily since I have a few spare tanks now.
Talking someone into upgrading their goldfish's aquarium (no worries, there are no bowls here, but needs more space as it's growing),
succesfully trying to finish cycling in betta's homes with Prime & waterchanges, and cycling a new tank for ghost shrimp....which is now a home for snails too. haha
Oh, and adding a few more decorations to the aquariums.
