Ok I got my fish afew hours ago to cycle my tank. The guy at the shop was like really experienced and knew wat he was talking about but I wanted to see wat you guys thought about 3 zebra danios 3 harlequin rasboras and 2 normal platy's cycling my 20 gallon long tank? Everything is going fine theyre all getting on fine with eachother the danios school with the rasboras and leave the platy's to themselves. I seem to be growing in confidence on a high if you will. Oh yea the 2 platy's are males so they wont add more babies to poop. Thanx*celebrate
