like i said in another thread, you guys may really like sand but be prepared to clean more..
I too prefare the look of sand but from the tanks I've seen they tend to look quite scuffy with all the brown poop showing up more visually on the white or yellow sand?
Just get corys, they keep the sand tidy. they constantly shuffle about in the sand witch nocks the poop back into the water movement (flow(current)) until it ends up being sucked up by your filter. My sand is sparkling clean.
I really believe sand is much easier to keep clean.
And as an added bonus corys are amazing to watch.
Are cory's the best option for constantly moving the sand about to gain what you mentioned above, or are there any other larger fish you could recommend as some of my fish have the potential take out smaller fish?
