Thanks guys!
I thought i had about 12-14 fish but after doing a head count with that pic, there seems to be more like 18-20. As they grow bigger, I plan on trading or selling at least 5 of them cause I don't really want more than what my bio-load can handle.
I'm using a Laguna Power Flo Filter Falls. I've pretty much jusr filled it up with lava rock inside. I also have another 50g plastic drum that I may use if needed.
Since I have a barebottom pond, should I vacuum out all the sludge and detritus on the bottom or just leave it?
