Samurai Gourami's are very similar to chocloate Gourami's. They need a low PH of about 4.0 - 6.0 also need low nitrates and grow to about 8 or so cm. They are moothbrooder's. They need to live in warm water between 26 - 30 degrees. Ive never seen them for sale but they are a very nice looking fish.
