I have a blue opaline gourami, i heard you can have them in a school, is this true? If so, what are some other types of gourami's i can introduce to my 75 gallon?
They are normally quite territorial, especially males. Some species like pearls and moonlights seem to do ok with conspecifics, but three spots (golds, blues, opalines, etc) don't normally get along well
