hi im very new to keeping tropical fish and found out from my grandad about cycling using fish, which i have now found to be very hard and unhumane, i had 2 danios in my biorb 60l for about 3 weeks and they were fine, i then brought 3 mollies just as i thought it seems ok just to find now that 2 mollies and 1 danio have died over night, all my water tests are ok but havent got a ammonia test kit yet as i thought my 6 in 1 test stick had it on there, ive had at least 2 danios in my tank for a max time of 4 weeks now am i nearly there when it comes to cycling using fish? i would remove all the fish but there is no way of anybody taking them off me...........as i previously said im very new and would love a bit of help, much appciation thank you
