Thank god I don’t have a bigger tank. I finally decided to pull out my rock work and eliminate my mysterious black mythrax crab that had been silently poaching my fish and dragging them away to their watery graves.
All the rock out, it took about 20 minutes (and a couple tea pots of boiling water) to find his burrow, and pull his boiled parts free. Once loose, it took another coule hours to clean up, place some new sand (which I had been meaning to do for quite awhile) and get onto the task of re-structuring my rock work.
In the end, I’m not sure if I love the configuration … but so it goes, one can never be fully content or else what would we have to work on next weekend!?
