Hello everyone, I have had this calm for a year and a month. It's my first clam that I ever kept.it looks good to me, I'm just wondering if the mantel is over extended. I know that's not a good thing. So please let me knowif it's ok. It's in a 150 gal tank on the sand bed. All my level are good, except for phosphate. I run go to keep it at zero or close to it
