PEARL GOURAMI (Trichogaster leeri) 2.5-3' A2405T

While often recommended as a community fish this is not always so. Some individuals can become very spiteful as they mature, while others remain peaceful. Males are territorial and will squabble amongst themselves, becoming very aggressive when breeding. It is best kept with robust fish such as barbs, larger characins, loricariids, loaches and other medium/large gouramis.
