Help ID some coral.

[critercrit]

So its sad to say due to starting a new job and a bunch of other things I have not been on top of my tank. Here are some pics of some coral I was wondering if someone can ID them and then let me know how to trim it down if they are bad. I am also open for other suggestions. I am new to reefing community and need as much advise as i can get.

This started as one stalk and now is taking over. What is it and how can i reduce it

Hello,
Do the polyps rise from a purple rubbery mat? If so it is most likely Pachyclavularia sp. It can spread quite rapidly and be hard to control. It is best to isolate it on a rock surrounded by sand. It can be trimmed as it leaves the rock and grows across the sand. It is also easy to remove from the sides of the aquarium.

Regards,
Kevin

Pink Star pollup will spread to anything it touches and irritate and cause other less aggressive corals to receed. It survives in very low light even. They also can give off noxios mucas if run rampant in small tanks. Tweezers, Kalk paste mix/AptasiaX (treat large areas in separate bucket before returning--don't need to OD the main tank...lol) will help contain its creep zone or complete irradication if desired.
