I've just started a new tank. I've added the salt and water, sand and LR
. The amonia spike is underway. I have already seen a bristle worm and some other things. I speared the bristle worm with a knife because I was told they were bad. I may not have killed him; he quickly got into a rock. Was this a mistake? I also have what looks like hair attached to the LR
swaying in the current. Is this good? Some of the LR
also has green bulbs on it. They're about 1/8" in diameter. Are these good?
