So my Oscar/jd tank currently has a black background and has a black gravel substrate. Due to the fact that sand is much easier to clean, I'm about to undergo the switch. The only issue is I'm debating on whether to go white or black or even a brownish color sand. The only reason I'm debating is because my Oscar was labeled as "wild" when I bought him. And since I've got him, he's been jet black with a orange eye before his tail. Making it difficult to see him. Do you guys think a different color substrate will make him more noticeable or even bring out the orange better? And I'd like to see pictures of the tanks too. Thanks
