Guys, i've got "something" growing on my live rock... it is a milky color and seems to be soft but firm... its nearly completely covered one whole rock... however, it's growing on the backside of it so i cant really get a good picture of it... gosh, it always seems like there's something new happening... thanks y'all!!!

In terms of sheer likelihood based on that description, it is probably a type of sponge.

based on the texture, i would say that it is correct... now, are sponges okay for my tank? how do i stop it from spreading? how did i get it? any information you have would be helpful.. thanks!!!!

okay, i was just surfing the web and i have seen several people describe what i might have.. they're calling in algae... but those forums do not have any answers...

It sounds like a sponge to me too, or some tunicate type deal. Most are beneficial at best and harmless at worst. The only ones to watch for are the ones that grow fast and grow in bright light, they are pretty rare, but can envelope corals.

Agreed, more than likely a sponge. Beneficial.

Thanks alot... that's exactly what it was... after further examining, i.e., i took it out and felt it, ha ha... and it felt exactly like a household sponge.. you guys are great!!!! i sure appreciate your input!!! keep it up!!! )
