Welcome to MFK!!
Asian aros are not legal in the US. There are alot available (it seems). However, you're just as easily ripped off by scammers advertising something they don't have. You send your money, receive nothing, and there's no recourse for you. You can't report them since this is an illegal transaction in the US.
You could get a jardini. They're inexpensive but, can be mean to tankmates. There's also the leichardti aro but, they're more costly at around $300 for a 3-5" juvie.
Check our sponsors lists. There's usually several batches of these aros available at any given time.
