I have a 60 gallon, and I have about 90lbs live rock, 60lbs of live sand. It has been running for about 4 months now. I had a bad case of alage, so the lfs said to put a lawnmower in to clean it up. He did great, it was clean in about a week. I noticed about 5 days ago, that his tail was looking strange. Now he has nothing. He'll try to swim around, but doesn't go too far. It looks sad. The overall appearance of the fish looks good, just no tail. |
