Hi all, i am a newbie to fish keeping so this might seem like a silly question..... I have a new 60ltr biorb which was filled, cycled & left to stand for four days, the water was tested by my local stockist & given the green light to stock fish, I now have two sailfin mollies (the male has a fungus infection which i am treating with 'king british fin rot & fungus treatment') and seem to be v.happy (other than the fungus infection of course) and two, Five Band Barbs who are very docile & inactive. Is this normal behaviour for barbs or is something wrong???. Water Temp is 25c.
