at the bottom of this picture is a mess of brown gunk looking stuff, where the sand is dug out some under the gray rocks. there is a bit of brown algae on the glass even level with the rocks, i cant clean it off at the moment, sorry. both rocks have white sand on them from where the parents dug out the hole earlier
heres a closeup - difficult to focus on the babies very well, my better camera will be available tomorrow.
