Lol you def have the betta bug! :P He's very pretty!
I'll give you some advice even though you probably don't want to hear it.lol I would see a betta that I absolutely loved and would just get it. 6 turned into 12, 12 turned into 20. One minute I only had 3 tanks, than I had 13. Keeping up with water changes was so stressful and time consuming. When one of my fish had internal parasites, I was told that ALL of them could have it because it's very contagious. If I just had 5 or 6 I'd be able to handle it, but I got so stressed out and overwhelmed because I could've had 19 fish with parasites.
Just make sure that you really have the time AND the money to put into these pets because they'll sneak up on you and before you know it, you'll be in a perdicament you don't want to be in. Just food for thought!lol I have lost 4 of mine in the last couple weeks and I've decided not to get any more because 16 is all I can handle right now.lol
