hey guys, i'm seeing some green stuff developing on the artificial seashell decorations in my tank, which i can only assume is algae. i mean, what else could it be? when i do my weekly tank maintenance, should i take the ornaments out and scrub them to remove the algae...? i've read that there are some fish that consume the algae, but my tank is not ready to add more fish yet. tank specs - fish in cycling with two danios, not yet complete the cycle.
