There is a post by a beginner who asks for advice on how to stock his 29 UK gallon tank (about 35 US gallons). He's interested in easy and hardy beginner fish. I suggested 1-3 schools of any of the following species: zebra danios, white clouds, harlequin rasboras, cherry barbs, neons, etc ... (basically any small peaceful
freshwater fish) - with white clouds and zebra danios as being the hardiest of this suggested group. I also think a pair of dwarf gouramis would be OK in a community tank with 1-3 schools (schools of 6) of the smaller fish. Only I think I've read somewhere on Fish Lore that gouramis need to be kept in a ratio of 1 female to 2 males. Is that correct? If he decides to have gouramis, should he have 1 female and 2 males? Or is it the other way around? Also, dwarf gouramis would be OK in a 29 UK gallon tank with, say, 6 zebra danios and, say, 6 harlequin rasboras or 6 cherry barbs, right?
