 crushed coral
I was hoping someone might offer some light shed on my problem. In the past, I had a 30 gal fish only tank with black moon sand and a very aggresive fish, recently i have restarted a tank at home away from work because of the excitement of my 4 yr old daughter. I started a fish only community tank with a couple of clowns and a tang. I also used white crushed coral and was told that i might need a different clean up crew than usual because of the roughness. any suggestions. Thanks in advance for the help. |
