</TD></TR><TR><TD vAlign=top width=197>AIPTASIA Aiptasia are pest anemones that often are found when people purchase cured live rock. Aiptasia is a medium-dark colored anemone with thin arms. These guys should be destroyed immediately, they can sting corals and damage them, and aipstasia can spread at an alarming rate. To remove them, you have a few options. the most common is to use a commercial product, like aiptasia-x and joe's juice. you just squirt the liquid on the aiptasia and they get killed. this is a simple and effective way. you can also use a blow-torch to burn off the anemone, this is also effective. Do not try to manually pick off aiptasia or use a cotton swab though, this will just break up the aiptasia and help it spread. You can also try aiptasia eating livestock to get rid of them, such as peppermint shrimp.

Barnacles are crustaceans that have jointed legs and shells of connected overlapping plates. Instead of crawling after food, they glue themselves to rocks, this is how we get them as hitchhikers. Barnacles reach out with little feathery barbed legs to strain out plankton and absorb oxygen.

Flabelligerids or bristle-cage worms are cylindrical tapering worms with a papillose body surface, which is encrusted with debris or covered with jelly-like mucus, and with rather disordered, long, hair-like chaetae.

The family Flabelligerids is also known as the Chlorhaemidae, and also includes the former Helmetophoridae. The head structures of simple gills and palps are important in identification to genus, but are often difficult to observe without dissection because they are usually retracted into the mouth in preserved specimens. Several subtidal species, which may be undescribed, occur in subtidal soft substrata and belong to the genera Diplocirrus and Brada. Elsewhere species of Flabelliderma are commensals of echinoids.

Usually free-living, but not extremely active. May be found enclosed in a transparent gelatinous tube or with the body obscured by adhering sand grains. Not known to form permanent tubes but may be found in the burrows of other animals or buried in sandy substrate. All flabelligerids appear to be surface deposit feeders.

Button polyps fit the same bill as zoanthids. They are polyps that live in colonies on your rock. they are photosynthetic, and need at least 3 watts per gallon of appropriate lighting. in proper care, you will have a large colony in no time. they are of no harm to other creatures and a nice freebie to your tank.

They are of no harm to other creatures, but they may accidentally step on corals. If you find one of these as a hitchhiker, consider yourself lucky. They retail for $20-$30 at stores.

If you find one in your tank, be careful and take the proper precautions. They can "snap" their strikers at the speed of a bullet, so they can easily break human bones and glass aquariums. they use their strikers to break the shells of inverts off so they can eat the meat inside. To remove one from your system, you can purchase a mantis trap. this is about the only safe way to remove one, do NOT try to use a net. they will likely break through the net and you risk getting injured. Once removed, you can place him in your sump, refugium, a spare tank, or try to give him away. try not to flush or kill them, they are intelligent creatures that are misunderstood.

With a flash light it is very common after procuring live rock to see many of these herbivores cruising on the glass and rock. Having a shell that only covers a portion of their body these seclusive snails only come out at night and are very beneficial to any reef tank. Once established they will release clouds of "smoke" which become fish/coral food or new stomatella if fertilized. If you do find that they multiply to fast you can collect them at night and many people will be willing to take them off your hands. I have witnessed maximum growth to be about a half inch for an adult specimen.

Urchins are spiny creatures that are interesting to watch. There are various kinds of urchins. some are round with short spines on them, some have fat pencil tips around them, and some have long thin spines. For the most part, they all act the same, and will scavenge for food and some even eat coraline. make sure your corals are anchored though, these guys are known to accidentally knock down corals while cruising around. If you find one that hitchhiked, consider yourself lucky, they often run for $15+ each.

Algae's And Other Stuff


</TD></TR><TR><TD vAlign=top width=198>BRYOPSIS The most common characteristic of this alga is the fernlike fronds resembling feathers. It is a sure sign of high levels of nitrates. The nitrates are not detectable because they are being absorbed by the Bryopsis itself. This can be very difficult to deal with. There are many methods of removal, my suggestion is watch your feeding, and use chaeto in your sump for nitrate exporting.

Bubble algae grows rapidly and can spread through the tank. It will tend to crowd desirable specimens out. Fortunately, it is normally possible to manually extract bubble algae and keep it under control unlike hair algae.

Most Caulerpa is maintained in filters or refugia where it can be confined. When part of it is harvested from the these systems, it is acting as a nutrient export mechanism. In other words, the nitrates and other compounds the algae absorbs as it grows is removed from the system when a portion of the algae is removed.

This macro algae has many benefits to a reefkeeper but generally its sole purpose is to absorb nutrients such as nitrates. Chaeto as it is sometimes called has the ability to host a whole slew of organisms such as pods, mini stars, and worms. Chaeto is preferred by reef tanks owners over Caulerpa because unlike Caulerpa it does not go sexual. When Caulerpa goes sexual it releases most of its nutrients it has absorbed and it could cause a tank crash. Using Chaeto will help fight nuisance algae.

It is desirable for most aquariusts because of how neon it is, and how bright and purple it can make live rock. Coraline growth takes a while in a new system, but with proper alkalinity and calcium levels it will soon enough come. some commercial products, such as purple up, will cause coraline to grow faster. this product is great and has a good success rate. If you decide you dont want coraline on your glass, the best way to prevent it is to scrape all sides of your glass daily, or purchase a coraline eating urchin if one is appropriate for your tank.

Luckily, it is easy to cure. There are a few causes of cyano. First, it is common in young tanks. when the tank is around 5-10 months old, you can expect to see a bloom. keep your skimmer going and feed a bit less during this time, and it will disappear. Try to manually pick it away from your corals to prevent damage to them. If you have a established tank with cyano, overfeeding and excess phosphates are likely to blame. Phosphates and excess nutrients are directly to blame from overfeeding, but phosphates can enter your tank by using tapwater. Most peoples city tapwater contains phosphates and alot of nasty stuff that will feed algae. This is why reverse osmosis and distilled water use is recommended in saltwater aquariums. There are a variety of red slime removers on the market, but they only mask the problem, not get to the root cause, which is why they sometimes are frowned upon.

Diatoms are a brown algae that will quickly spread. They are common in new tanks, or established ones where tapwater, overfeeding, and silicates are present. to prevent diatoms, use RO or distilled water, have a good protein skimmer, and do your weekly water changes. in a new tank, ride it out. do not add a algae eating fish like lawnmower blennies. algae eating fish will eat all the algae, but when there is no more algae left, they will starve.

Dino's occasionally bloom in reef aquaria, and they can be toxic to invertebrates and fish. They form nearly colorless to rust brown or green gelatinous mats and films that trap oxygen bubbles. They can also be present in large numbers in the water column and on the surface of the water during a bloom. They coat bare surfaces so quickly that it is futile to siphon them off."

Most Caulerpa is maintained in filters or refugia where it can be confined. When part of it is harvested from the these systems, it is acting as a nutrient export mechanism. In other words, the nitrates and other compounds the algae absorbs as it grows is removed from the system when a portion of the algae is removed. Some species, especially Grape C. can go sexual and disintegrate overnight adding substantial biological load to the tank. This can be minimized by heavy pruning which seems to retard this tendency.

Usually dark green, grows quite long if left unattended and spreads across your tank rapidly. A number of things may have contributed to it getting a foothold in your system. Your nitrates or phosphates may be too high. Find that source, you may be over feeding. I use Chaeto algae in my refugium to suck up the nitrates and starve the Hair Algae.

Halimeda is probably the best macro algae to have in a reef tank. It is slow growing, so it cannot easily become a nuisance. Halimeda requires fairly high calcium and Alkalinity levels similar to stony corals to survive. Halimeda also prefers higher intensity lighting.

Glad you posted this gaz because this morning i saw on the glass of my tank what looked like a tiny white MEDUSSA WORM never seen something with so many loooong legs if thats what they are.Are they a good thing to have?i no i would have had fun trying to explaine to you what i saw:roflmao:
