i know that this thread should be in the tank forum but in my opinion, it would be better to ask you guys for my fish is an aro.. the forum there caters to all fishes..
my tank is very plain.. just my aro and the filter.. i was thinking of putting sand into my tank.. my question is, which is better white or black? but i am a bit hesitant because i am not sure if the undergravel filter really works and what if the accumulated waste will just hide under the sand.. that would make my fish's life miserable..
i'm also planning to have a black background for my tank.. i have a 6 inch golden jardini.. what light color is best suited for my aro?
p.s. besides your personalized filters, it must really be hard cleaning your tank right? i mean with all the ornaments in the tank..

Personaly I don't like under gravel filters becuase 1 you can't get sand and 2 if you have a fish that likes to dig (if not deep enough) it won't be able to. If black and white are your only options then I say black, because most light color sands and gravels reflect light, which normally bleaches a fish's colors and in some theories glare at the bottom of the tank causes down eye (DE) in aros, but this has been proven false. and I recommend another filter and put some tall blade leaf plants and flat oval rocks will make it look nice to.
