It's also available everywhere here in UK/Europe in all chain pet stores, but that's a bit difficult for the USA members unless they're planning a vacation here soon. There's also a few sellers on eBay UK that will ship it to the States. Royal Mail International is very fast in my experience, so it's not a huge risk ordering from overseas. Maybe I should buy a industrial-sized carton of the stuff and post it to everyone on the forum when I come to the States for vacation this winter, haha.
Anyway, back on topic. Atison's Pro is great, but that's if you can find it. New Life Spectrum's Thera-A (there's loads of garlic in this one, always a good thing) or Betta Formula is hands down the best, ingredients-wise. My betta prefers Atison's Pro, but looks more healthy when he's on NLS exclusively. A bit expensive compared to Tetra and such, but well worth it.
