Looking good! But amazon swords end up like this
and are heavy root feeders. It looks great right now though! You can always return/sell it later if it gets too big or starts dying. Also, did you know about plakat bettas? They're just short finned bettas. I don't especially like bettas either that can't swim, though they can be gorgeous. Here's my baby. I can't resist a chance to show him off.
I've heard that veil tails are actually the least inbred and are the mutts of bettas because the droopy tail is not as desirable anymore.
OH and ghost shrimp can turn out to be huge evil monster shrimp that attack fish. Or they could just gnaw on the bettas fins while he lays down. Watch out for torn fins.
