Hi guys,
I'm looking at changing around my big tank a bit before my pearl aro moves in.
I currently have dark (brightwater) gravel in there however I plan on painting the back black soon and I'm worried it'll look a little dark so was thinking of changing to sand. Bare bottom would be heaps easier but I don't want it looking too clinical.
I've heard having a bright substrate such as white sand can be a contributing factor to the development of drop eye - in your experience is this true? If so, I definately don't want to risk it and will stick to dark gravel and maybe choose a different colour for the background such as blue.
Also, what do bichirs prefer? I understand the catfish will probably prefer the sand.
Stocking is pretty much going to be aro, catfish and bichirs, ghost knife and a school of red and gold severums.
