Very good suggestions! I'm contemplating the Guianacara instead of Red Head Tapajos in another tank. Do they sift sand? Gosh they seem hard to find tho, anyone have suggestions on where to find any? Rapps isn't even able to get them at the moment.
The Red Ceibal I like as well, what about the cool period I've read about?
Do the B.cupido sand sift?
