I'm going to purchase a 90 gallon tank for some festae that I have and I'm debating between pea gravel and pool filter sand as a substrate. I've had them in tanks over PF sand and 3m black quartz previously. The quartz made them darken up considerably IMO, and the PF sand I had them over is white with a grayish tint. I'm curious to everyone's results color wise( if any) in their fish with festae over pea gravel vs a very bright white PF sand. Thanks
