Discosoma: card and info on discosomes. From the red discosome, to the blue, green discosome ... what to do if it does not open or in the case of infesting discosomes (how to eliminate discosomes from the marine aquarium).
In the marine aquarium there are many specimens of the discosomatidae family that we host. Each species should have its own characteristic card.
At the taxonomic level, idiscosomesbelong to the class of anthozoans (Anthozoa), arehexacorals of the orderCorallimorpharia. Like allcoral morphs, they can become weeds and they are difficult to removefrom the aquarium because they easily propagate by cuttings, so the attempt at mechanical removal does nothing but give life to more specimens.
Red discosome, green discosome, blue discosome
The species of discosomes most common in oursmarine aquariumare those of the genus Rhodactis (such as R. rhodostoma, R. mussoides or the very common R. indosinensis, theblue discosome or purplish R. inchoata, the green discosomeR. howesii) and the homonymous genus discosome. The species of the genus Rhodoctis do not have a streaked or smooth surface but always indented. While in the genrediscosomewe find specimens with a striated surface (also in this case, very common is thegreen discosome striated) or dotted (discosoma punctata), the green discosoma (Discosoma nummiformis) although the most common species are that of the Discosoma neglecta, D. malaccense (brown discosome), D. ferrugato (red discosome), D. coerulea (purple discosome).
I'msoft coralseasy to breed so much that they can also be adapted in recently started tanks. They require moderate water movement, which is why thepositionit must not be close to the movement pump. The position must ensure moderate lighting, and, for some species, even weak. Indirect lighting is always to be preferred, so they can be placed at the foot of other soft corals, perhaps of the sarcophyton genus, capable of guaranteeing some shade.
If a discosome has broken off, you can place it using coral glue. In the article "coral glue" you can seehow to glue discosomesto a rock, even if the adhesion of thesecorallimorphsit is quite easy and you can use a classic pin (I'll explain how to do it in the article on coral glue).
Discosoma does not open
If you have recently introduced the discosome into the tank, do not worry, it can be normal. THEdiscosomesthey need an acclimatization time of at least 30 minutes, but this is generally not communicated by the shopkeeper. Thus the discosomes go through a period of re-adaptation and fail to open.
They tolerate a fairly wide range of temperatures even if the ideal range is between 22 and 28 ° C.
They can be photosynthetic (autotrophic) but their feeding in the aquarium is mainly based on the absorption of nutrients such as microplankton and other debris of organic matter. Incardspecific for each species, it is noted that they have a need for magnesium, calcium, strontium and trace elements such as iodine. These are trace elements that should be present in any well-kept marine aquarium, so it can be said that they have no special needs.
How to eliminate discosomes
THEdiscosomesthey can be pests. A good way to limit its growth is to introduce activated carbon into the filter but this strategy will limit the growth of allcorals in the aquarium, both soft and hard.
THEdiscosomesthey can becomeweedslike xenia pamping and others corallimorphs that rediscover a perfect ecological niche in your marine aquarium. A tub upholstered withdiscosomesofcolorsdifferent can be quite fascinating, however when the discosomes start growing uphard corals it's a big problem. Prolonged physical contact between hard coral and discosome causes not only limited absorption of nutrients by the hard coral but, in the long run, also degrades the hard coral tissue to the point of death.
To eliminate the infesting discosomes it is possible to use the same technique that I have suggested to eradicate the glass anemones of the Aiptasia genus, it is even possible to use the same product. For further information, I refer you to the articlehow to eliminate aiptasias.
If you don't want to buy products, you can continue with a do-it-yourself method but it is not without risk. It consists of injecting calcium hydroxide mixed with osmosis water into the body of the discosome. Basically you mix calcium hydroxide with osmotic water until you get a milky mixture, use it to fill a syringe and then inject this liquid into the discosomes, in every single specimen that you want to eliminate.
During the treatment you should deactivate any movement pump and move the water outlet pipe of the filter to the "neutral" position.
