So, I went to buy some live rock today that I found on craigslist. My tank is a 20 gallon high tank, and I had about 4 pounds before. Now, I bought some new very nice live rock that had been in an established tank for about 3 years. The live rock has tons of green and purple coraline on it in addition to various other critters. I did go through it and took of some of the bubble algae that was on it. I did see a few bristle stars, small ones though. Those are beneficial to my tank am I correct? In addition to the rock, he gave me a good piece with some mushrooms on it. The major mushroom is a green mushroom I believe and it is about 1 inch in diameter and there ia a blue one about an inch in diameter and maybe about 10 small ones like half an inch or under. My lighting is only 15 watts fluorescent from above and 15 watts from the side pointing at the live rock and those corals. Will this be anough lighting? Also, do I need to feed the corals anything or is there any special care I must give them? Oh, and now, I have about 15 pounds for my 20gal and I got all 10 pounds for only $23!! Wow hehe..
thanks
