I saw this amazing critter on the glass last night actively moving with its two "legs" and catching stuff from the water with its "parachute". Anyone seen this before? http://photo.gerasimov.net/main.php?g2_view=core.DownloadItem&g2_itemId=6288&g2_serialNumber=2...

Thanks guys, you rule! One damsel fished out with the bottle trap, one to go.

You think the damsel will not find its way back out?

I have a 95Gal reef tank with lots of LR. I was stupid enough to buy a pair of Fiji Damsels. These devils are terrorizing every living creature in my tank. I tried the net, but they are too fast for me. I tried the trap made out of transparent plastic with a door made of many long pieces of...

My PO4 is 0.25-0.4, its hard to say more precisely with the nutrafin test I am using. This is admittedly non zero, but should not cause tissue breakdown. I do have a slight cyano problem, and some of it is on the zoas. This does indicate some overfeeding on my part. I will try to do bigger...

No anges. I only have two mandarin gobies and four damsels (two blue and two fiji), I am not big on fish. I like inverts and corals. I did look at the during the night, nothing suspicious. The only remotely possible suspect is a pistol shrimp that was a hitchiker on LR. I do have blue legged...

The problem is that this is happening all over my tank. I had 6 clusters of zoas scattered all over, and i only have a handful of zoas left that are alive. Some of them were on a rock with a larger (predatory-type) green polyp on it, and he's doing fine.Some of them were alone, and they are also...

I have this growing on my LR and floating freely in my refugium. It looks pretty nice, and it harbours a million of pods. Anyone has any idea what is it? Here is a close-up: The color on these pics is a tiny bit off. In reality they are more brown then golden-brown. To the touch they...

Any ideas folks? Any at all?

After doing fine and multiplying for 5 months, my zoanthids all of a sudden started closing up and dying. I maintain Ca at 450-480, ph 8.1-8.2 depending on time of day. I do regular water changes of 10% every other week. I have a large heavily lighted refugium, and a prism skimmer. The system...

Florida cup coral? This looks to me like a Florida hidden cup coral. They are frequently mistaken for glass anemones, but they do have a skeleton unlike the anemone. Sure way to tell is to gently poke it with something soft (like a brush) and see if there is a "crater" left when it hides. A...

I can see the photos just fine. Anyone can see them or is it broken for everyone but me?

Tonight I have noticed swarms of tiny critters actively jumping all over my 95Gal. reef. Caught one and made this photo under the microscope: I think this might be spawn of my pistol shrimp, but i would be delighted to hear expert opinions. Here is another shot: The critter is about 1.5mm...

Thanks a lot!

This little guy is approx. 1/2 inch long with mantle extended. The shell is hard and is approx. 1/4 inch long. He absolutely hates light. And he like to broadcast sperm in moderate amounts in multiple pulses. No eggs so far. Appears to be herbivorous, and his mouth looks like other herbivorous...

Check out low wattage metal halide. They go as low as 35 watts. Search google for metal halide MP35. You will need a special ballast for this bulb, but you can screw it into a standard incandescent fixture Make sure the fixture can take high heat. The socket has to be ceramic, and all other...

You can buy distilled water by the gallon in jugs at your local grocery store. This is expensive imho. Buy a small RO unit if you can afford it. I have purchased a 4-stage RO unit a few years back. My wife now makes coffe only from RO water. We use probably 2 gallons a day of it for non-aquarium...

Yeah, they do not look too exciting, but check out that size! I think they can filter a gerat deal of water in much less time then an average clam.

If you have not caught that yet, it's a porcelian crab, not porclean :) And yes, it's one of the best crabs to have in a reef tank if you have to have a crab. http://www.mbayaq.org/efc/living_species/default.asp?hOri=0&hab=4&inhab=420

Anyone keeps oysters in your tank? There is an auction on ebay for 3 of them. I was just wondering what you all think of keeping oysters.

It is really worth investing in a set of test kits, IMHO. When I got my first saltwater tank started, and bought test kits a few days later, my Ca++ level was at 240 mg/L (ppm). I stopped using that brand of salt since then, and was able to correct the problem fairly quickly, but if you do not...

No pics in this post... It would really help to id the thing if we can see pics.

Looks like a pink-tipped anemone, Anthopleura elegantissima. What size is it?
