Help! somethings wrong with my yellow TANG!!!!!

[targa81]

While this is the pot calling the kettle black, even I wouldn't put two tangs in a tank that small.The regal must be beating him up bigtime. My tang amongst others will be going into a 150 ASAP. I got my hippo when he was a baby but despite my best intentions 5 years have elapsed and he has way outgrown my 50. I would be hesitant to put two tangs together even in a large tank given the chance they would fight.BTW, although the cause of your tangs tattered fins looks like trauma, overcrowding can also lead to disease eg. Ich which also causes this. Mike.
