They are eating my coralline algae. I have noticed a huge decline in the algae, and I have a very well established tank. I'd like to keep my coralline lol

Yea, I am wrong about the name. Any idea on how to get rid of them?

I have noticed a few dozen (that I can see right off hand) of the little bitty starfish. I was wondering what (if anything) eats these things. Since I have seen them, I have also noticed my coralline algae is being eaten. How do I get rid of these things without tearing my tank apart?

I just added some new corals to my tank. They are Elongata Xenia, Galaxia, Fire and Ice Zoas and something called Sunshine. They look like zoas, but they have VEERRY long hairlike skirts, and they are sunny yellow. They were all thriving and healthy looking in the tank that we bought it from...

You shouldn't have corals and anemones in the same tank for the simple fact that anemones move around and sting your corals.

get that thing out of your tank immediately if you think it was dying, because your whole tank could possibly suffer. When they do die, they kinda turn inside out and form a ball of black gross stuff. I had one die about 2 years ago and haven't had one since.

My hammer coral is far away from any of my zoas, because I do know that they can sting. The zoas that are thinning are very far away from the hammer, atleast 18 inches. The zoas that are left are very open and still acting normally to the passing fish and critters. The colors are still as bright...

I have a unicorn tang, a regal blue tang, percula clown, lyretail anthias, mandarin goby. I have a Marineland pro series light with a 150 watt 20k halide and 4 39 watt actinics. I just changed my bulbs, but the thinning out started happening before I did that, so I don't think I'm burning them...

I have several different types of zoanthids in my tank, and they have all been thriving for a long while. Just a few weeks ago, I noticed alot of them have been plucked off my rock and some are just floating around, or are in a corner of my tank. Now, my pink ones (which just so happen to be my...

Thanks. Now, have you ever seen one like this?

I guess I have been saying the name of the starfish wrong, so someone please correct me so I don't sound like an idiot anymore.

I saw this on the overflow box in my tank. I have about 4 or 5 small astrea starfish that I know of, and they are about the size of a pea or smaller. This thing is about the size of a quarter, and as soon as I turned the lights on over my tank, (I was changing the bulbs) it went back down into...

That's what I was thinking, but I wasn't completely sure. Thanks.

a friend of mine has decided to start a saltwater tank. I have had mine running for a few years and I can't remember if you do water changes when a new tank is cycling or not. Advice?

try to stay away from feeding him guppies. They don't have the nutrition lionfish need. The lionfish I had liked to hide alot and I read that the upside down position is normal for them. You haven't had him that long, so just give him some more time to get acclimated to the tank and the fish...

Joy13, I looked at that link, and those corals are beautiful!!!!

the light i have it under now is a marineland pro with a 150watt 20k halide (my bf knows exactly what it is). the tank we got it out of had some kind of new LED system on it.

the other two frags are doing good. they still have their color and look fine. i guess we did lose this one, but i don't think i will get rid of it just yet, just to make sure.

It's right under the halide!!!! It was a purply color when I got it. I said that in my original post. IDK what to do about it. My LFS said you could see it's skeleton if it died. I don't even know what that would look like. I guess I'll give it a while longer and see what happens. Thanks for...

where did everybody go?????

I didn't know brains had to "eat". I thought they just got what they needed from the calcium and lighting. Hm. I was thinking about getting one.

I had a white pincushion urchin. It was in my tank for about a week and I got rid of it. It was eating all of my coralline algae.

What kind of camera are you using to take your tank pictures?

I took about 20 pics and this is honestly the best picture I could get with the camera I had. sorry about the fuzzyness. I hope someone can still help me.
