I transfered my molly fry (around 15) in to my 5gallon a couple of days ago and noticed yesterday the tank was decidedly dirty. so i've done a water change this morning and vacuumed the gravel and yet it's still dirty.
so if i clean it again later today will it do any harm?
is there any way of stopping this happening again?
