Sorry about the dwarfs, unfortunately they seem to be a weakened strain nowadays. Honey gourami are a much better option.
Cheerio,
I agree, I should have done more research before I bought the Dwarf Gouramis but I'd always wanted them and wrongly believed that the new LFS where I got them had a "good source". In hindsight, I don't think there is any such thing anymore when it comes to that species.
Hopefully these will be as hardy as the Pygmy Corys and Ember Tetras who have been happy in the tank for more than a year now...
