So I have stocked my 10 gallon now with some black sand, live plants, 6 neons and 3 golden wonders. I currently have the filter running and everything but I was wondering about all this other stuff like Powerheads and Air pumps...do I need any of these? Will it be benifiecery? My Golden Wonders stay at the top of the tank for about 90% of the day, would they like/dislike the current from the powerhead? Thanks in advance...
