Ive just set up a tropical tank and put fish in for the first time a week ago 2 gourami and 1 male fighter they all seem ok but one of the gourami seemed to have a white mark on the top fin and now it looks as if a piece has come away.I read some leaflets that suggeted fin rot but im not sure wot do do now. Ive checked the water and there doesnt seem to be a problem there. Im worried about it spreading to the other 2 fish and im now unsure weather to put any more fish in. If anyone could give me some advice i would be very grateful
Thanks
Thanks
