Hi everyone
I just got my first coral into my tank
And i noticed that i have a hitchhiker attached to the rock it came with from my LFS
Can anyone identify what it is and should i remove it?
I also have a question about any recommendations for adding bottles of magnesium and calcium because i tested it and its quite low. What would be recommended to buy?
And any recommendations for care tips and when should i be concerned?
