Okay went away Friday to see son at school, came home Sunday. Check out tank. firefish added 9-Nov still there looking good. Can't find PJ cardinal added 9-Nov. Bluespot Jawfish added 9-Nov is sitting in front corner with sand all removed, not in his usual den under the rockwork. Take a look at him and something has been chewing on his tail. Pic below.
Tank mates peppermint shrimp, boxing crab, a few scarlet hermits, asst'd snails. Can't figure it out. No snapping, popping in the tank ever. He is eating and moving around fine. Just gonna keep feeding food laced with Selecon and see what develops. A real quandary. Not the best pic. Not staying still enough. What is chewed is the top half of his tail. Bottom half still okay. Whatever happened it got right into the meat ahead of his tail about 1/8"
