Hello! I am the proud fish momma of Alaric (baby betta male, still growing so unsure of tail type at the moment, but a beautiful blend of blue, purple at times, green, and red) and more recently of Gaston (adult orange pineapple VT male). I was planning on upgrading Alaric to a 5 gallon, but that was before I rescued Gaston. Now that I have the two of them I've been going back and forth on whether I should get a 5 gallon to split? Or if I should get a split 10 gallon. I've never had a split tank before so I'm looking for some opinions, advice, and pros/cons from those more experienced than I 
Before I found Gaston, I was planning on a 5 gallon, so I bought a mini 3 gallon filter because I know bettas don't like a lot of current in their water. If I go with a 10 gallon for the boys, I wouldn't use the 3 gallon filter - but would a normal 10 gallon filter be too strong for them? (Random thought, could there be a potential for two 3 gallon filters in a 10 gallon?) Alaric's still a little guy and just isn't big enough to swim against hardly any current. Any brand recommendations based on whether you think 5 gallon or 10 gallon?
I've got rocks and decorations already - but if I go with a 10 gallon I might pick up a couple more so they aren't struggling to find a place to hide. I also have a 50 watt adjustable heater which I think will work for both a 5 and 10 gallon tank.
As for a divider - I've seen both commercial ones and 'homemade' ones of sorts. Any comments or pros/cons on either of those?
I'm trying to keep things on the cheaper side too, though I will buy what's necessary and best for my boys
Sorry for all the questions I've had (along with my parents help) freshwater aquariums all my life, but the biggest one I've had on my own is a 2 gallon. None of them were a split tank with bettas either, so this is a bit of an adventure to me. I want to do right by my boys, and get some good experience in now since this is quickly becoming a hobby that I'm finding I really enjoy, and hope to keep it up.
Thank you so much in advance for your time and help!
