The animals seen as primary consumers include zooplankton, which is made up of the small larvae of larger fish that grow to become consumers at different levels of the food chain. Urchins will eat it, but you're not going to get your tank walls clean without a razorblade. It’s still a bit of a mystery, but the crabs had been living in the aquariums for at least several months and had cleared out all of the bubble algae—maybe they were just really hungry. Red algae are also classified into some species like dulse, Irish moss, coralline algae or laver, etc. [5] Many are typically encrusting and rock-like, found in marine waters all over the world. Their calcified encrustations reinforce dead coral skeletons and fill cracks in the reef substratum, contributing to reef formation and cementation, maintaining a complex reef surface and reducing reef erosion. Most urchins will eat algae of some sort, with the most commonly offered species being consumers of both microalgae and filamentous algae. Only calcareous algae (such as Halimeda or coralline) or a controlled growth of macroalgae, usually tucked away in a refugium, is considered acceptable. These patches of pink "paint" are actually living crustose coralline red algae. Crump, R.G., Morley, H.S., & Williams, A.D., 1999. They also tend to shift from grazer to carnivore over time; in fact, they may attack and eat small fishes and tear up corals to get at any food inside them. The cheapest and easiest way to add coralline algae into your tank is to introduce a live rock, or anything else that’s encrusted with the algae, including snails! This species grows to a size of 2 or 3 inches (5 to 7.5 cm) and looks quite fancy. Many coralline crusts produce knobby protuberances ranging from a millimetre to several centimetres high. They are often very slow growing, and may occur on rock, coral skeletons, shells, other algae or seagrasses. Coral Reefs 28: 881-891, List of coralline algae species in the British Isles, "A coralline-like red alga from the Lower Ordovician of Wales", "First freshwater coralline alga and the role of local features in a major biome transition", "Monitoring deep Mediterranean rhodolith beds", 10.1666/0094-8373(2000)026<0651:DOCRAO>2.0.CO;2, 10.1306/212F7554-2B24-11D7-8648000102C1865D, "Morphogenesis and generic concepts in coralline algae: A reappraisal", "Evolutionary history of the Corallinales (Corallinophycidae, Rhodophyta) inferred from nuclear, plastidial and mitochondrial genomes". Brown semi rigid but slippery macro algae. ), and the very popular tuxedo urchin (Mespilia globulus), all of which can be kept in reef and non-reef aquariums. They don’t damage corals and such, or eat coralline algae. [citation needed]. A close look at almost any intertidal rocky shore or coral reef will reveal an abundance of pink to pinkish-grey patches, distributed throughout the rock surfaces. Only one species, Pneophyllum cetinaensis, is found in freshwater. I don’t care if they eat coralline algae either. Since coralline algae absorb calcium, and often shares a tank with other organisms that do as well, you should monitor calcium levels monthly. The calcite normally contains magnesium (Mg), with the magnesium content varying as a function of species and water temperature. It’s also very interesting because it manages to keep some of the photosynthetic structures (chloroplasts) from the algae it eats and uses them in the same way that corals use algae to get food. Coralline algae are red algae in the order Corallinales. For example, a recent book on the seaweeds of Hawaii does not include any crustose coralline algae, even though corallines are quite well studied there and dominate many marine areas. Both types contain calcium carbonate in their cell walls, which gives them a hard texture and their name. Wave action is most severe in the shallows where seaweeds must be firmly anchored, slippery smooth and tough but flexible, to resist the wrenching forces of waves. Smith, M.R. It comes in many forms, ranging from an unattractive green film of microalgae on the glass to fleshy, vine-like macroalgae that grows over rockwork and smothers corals. Hey guys I started getting some green string/hair algae. In addition to numerous fishes that can help keep algal growth in check and an aquarium looking sharp, there are algae-eating creatures that can help out, too, including various crabs, sea urchins, sea slugs, and snails. Coralline Algae also provide food for invertebrates like Sea Urchins and several Hermit Crab species. They’ll also eat microalgae, but unlike the fighting conch, they will crawl all over everything in an aquarium, cleaning up as they go. The cell fusions provide the matrix for the regeneration of bone tissue. The first coralline alga recognized as a living organism was probably Corallina in the 1st century AD. Epithallial shedding in most corallines is probably simply a means of getting rid of damaged cells whose metabolic function has become impaired. The perpetual growth of the unwanted algae in marine aquariums is one of the biggest headaches for hobbyists. Coralline algae normally occur in the intertidal zone and have some unique features including: large and dome-shaped cap cells (Pueschel and Trick, 1991), conceptacle containing reproductive structures, and abundant spermatangia formation from short filaments on the floor of the conceptacle (Lee, 2008). What will it eat when it eats all the algae? The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or gray-green. These are the only creatures I know of that will consistently eat nuisance bubble algae (Ventricaria ventricosa and Valonia spp. ), long-spined urchins (Diadema spp. That being said, there are some that stay the perfect size, eat nothing but algae, and don’t cause any problems. The corallines were thought to have evolved from within the Solenoporaceae,[22] a view that has been disputed. Red algae such as dulse (Palmaria palmata) and laver (nori / gim) are a traditional part of European and Asian cuisines and are used to make other products such as agar, carrageenans and other food additives. This is particularly significant in Britain and France, where more than 300,000 tonnes of Phymatolithon calcareum (Pallas, Adey & McKinnin) and Lithothamnion corallioides are dredged annually. The larvae of many reef organisms, including hard corals, favour CCA as a substrate for growing on. Seahares are avid algae eaters and might control some of your algae.
