i found some very nice looking angels - i bought them and put them in my q tank 20 which is looking relatively healthy now - i put in a divider keeping the angels on one side as the resident silver dollars began nipping their fins - one fish now on the other side is being treated for slight mouth fungus - has had it for a while - i am treating the tank with melafix - but do i have to wait till the fish with MF is ok before i move the angels or not? i plan on keping them in q for 3-6 weeks before moving them to their new home in my big tank - also now that the divider is in place how do i medicate the tank ? the divider has very small holes in it - but will the meds flow through ok? the directions say one tsp per 10gs the tank is a 20g so thats two doses - so shoul i just do one dose on each side of the tank?
