    Hey,
    I just finished buying all of my live rock! I have a little more than 90 pounds in my 90 gallon now and was curious as to whats on them. I believe most of them are a type of sponge? Pretty sure the second picture is just coroline algae. How do you tell whats alive or bad? TIA

    second pic is type of hydriod, pretty common, usually grows in caves
    next two pics are sponges, good filter feeders, shouldnt be out in the light though
    last pic looks like algae of some kind
