Hey so I have a 32 biocube reef with 2 clowns, 3 bangai cardinals, 1 firefish, 1 watchman goby, 1 skunk cleaner shrimp, 1 peppermint pistol shrimp and a tiger conch. Do you think a six line could be added. Ive heard mixed reports on them and wanted to be sure. If not I'm happy with how it is stocked so I'd be completely happy with not adding anything.
