Can you put sand in an Oscar tank. I have an Oscar in a 75 gallon tank, and I was thinking about swiching the substrate. I currently have gravel. I like the look of sand, but I don't know if it is good in a tank with an Oscar? Will it really show up the poop? My gravel kind of camouflauges the poop. I do weekly gravel vacs though, so it is not really a problem. I just don't want the poop to be staring me in the face!!
Will it get into the filter, since the Oscar digs and will probably kick it up? Also, how do you clean it, without sucking the gravel out? Does it pack down and create and anaerobic environment so that bad bacteria can grow? Sorry for all the questions, I just don't want to change out the gravel, and then realize I made a big mistake.
