New Pearly Jawfish Pair

[OrionN]

I think you are right. The one with the two spots under the mouth is the male, except that they look identical except in breeding season. Out of season, the spot will disappear.. When I had my, I added lots of coarse pebbles for them to use to build a burrow. I would get get shells (oyster shell etc..) and smashed them so that they have the flat pieces that they need. From your pictures, I only see fine sands and rock.
