Comments – nice little active fish ... great for a 10/15/20L species set up ... likes sand and needs snail shell homes of suitable sizes (sm-md-lg-etc..)...males are active harem spawners and defend territories
Personal Experience - the white 'sand' stuff in the pics is aragonite (to buffer high/hard) and is mixed in with estes black sand for a pleasing salt and pepper effect
