hi , i have a 190lt aquarium + only want to get rummy nose tetras , neons , harlequins , hatchet fish + kullhi loaches + was wanting to know how many of each i could eventullay have in this size of tank...thanks
Rather than mixing smaller groups of several species, I would stick with one or two and build up their numbers. Shoaling fish always look more natural in a large group. As for the Khuli loaches, these should be kept in groups of around 4-5 as a minimum.
