- Aquascaping Lab by Tommaso Perini and Serena Sacchi, presents a video on alimentation, growth and maintenance of corals.
Corals are, mixotrophic organisms, they feed both autotrophic by means of zooxanthellae, which in a heterotrophic, with the help of phytoplankton, zooplankton, bacterioplankton or food provided by us, using direct methods such as providing chopped shrimp, fish, shellfish obviously the right size categorized according to the polyps, or indirect methods such as the use of funds colonize by annelids and small crustaceans. Another indirect method is to create the so-called "refugium", a tank connected with the main aquarium, where there are no predators, no excessive movement of water, with the presence of specific algae.
The correct nutrition is therefore a balancing of amount and timing, between autotrophic and heterotrophic nutrition, usually during daylight hours autotrophic, and during the dark hours that heterotrophic.
Zooxanthellae:
Zooxanthellae are photosynthetic algae, unicellular microscopic in size (about 5 microns) that live in symbiosis with many species of coral and are localized in the tissue exposed to light. They live in symbiosis with the coral polyps because they get from those nutrients such as phosphates, nitrates, carbon dioxide CO2 and thanks to photosynthesis, triggered by the presence of light, are able to produce the molecules needed to the nutritional needs of the coral, providing oxygen and carbohydrates. Zooxanthellae, thanks to a high concentration of pigments such as chlorophyll and carotenoids are also the "responsible" of the different colors of corals. that colors are more effective under water where the concentration of blue and green light is higer. In aquarium, usually they make 60-80% of the energy of coral needs, that's why is required a strong illumination, but be careful because in some cases excessive exposure to light can cause intoxication of excessive production of oxygen.
Phytoplankton:
Phytoplankton is a autotrophic photosynthetic organisms present in the plankton and using solar radiation as a source of energy. It is located at the base of the food chain in most aquatic ecosystems and plays a vital role providing the material and energy flow necessary for the maintenance of heterotrophic organisms. Unlike what is often believed, phytoplankton is not much used by calcareous skeleton corals (sps and lps), while it is essential for the sustenance of soft corals, Zoanthids, Gorgonians and aposimbiontic corals, those who do not have zooxanthellae, are the ones in the aquarium they necessarily need service daily to survive, can not count on any photosynthetic symbiotic algae action.
To cultivate phytoplankton, we can use ordinary plastic bottles, putting them in front of two or three 20W neon, at least 15 hours a day and airing the bottle with a bubbble tube without air stone, posizioned on the bottom of the bottle, with a moderate power, we can use olso special kits. The water inside must be chlorine-free, with a pH of not below 7, a GH of at least 10, and a temperature of about 25 ° Celsius. You will add chemicals elements to promote growth. The proportions are about 20-40 cc of phyto in 1 liter, and after 10 days you will see that it is ready by dark green, at this point we can use our phyto to feed the zooplankton.
The most popular algae are: Nannochloropsis, Isochrysis, Tetraselmis, Chaetocerous and Chlorella.
Some things to see if you are feeding well your corals; if the coral will darken, in conditions of optimum water values and proper lighting, we must increase or change their diet. If the polyps are retracted and the corals start to lose tissue or takes a quick whitening it is possible that there is a wrong or limited heterotrophic nutrition. Then replace or supplement immediately.

nice video
Bellissimi...non pensavo fossero così belli e soprattutto coloratissimi.
Ci fate sempre vedere pesci,piante,coralli (in questo tutorial) che sicuramente in natura non vedremmo mai.
Bellissimi
Grazie mille!
bravissimi come sempre !!!
Grazie mille Arturo!
buon video mi ha piaciuto tantissimo!!!!
Grazie infinite
Ma siete bravissimi anche sul marino 😁 oliver knott secondo me é invidioso 😂😂
hahaahha grazie per i complimenti!!! non ti allargare dai!!!! :-)
un argomento estremamente bello a livello acquario filo è la storia della acquariofilia se faceste un video su questo mi commuvereste
buona idea e grazie per il suggerimento!!
Salve vorrei chiedervi un consiglio sulla mia sinularia comprata e da poco messa in un marino da 20l presenta sui rami più alti delle macchie marroni gelatinose che si muovono al apparenza sembrano vermi parassiti piatti secondo vuoi come posso eliminarli senza ferire il corallo???grazie attendo risposte ...
siete veramente bravi ! ma perche non fate un video dove spiegate che tipi di coralli esistono ( lps - sps - molli ) e in che tipi di acquario poterli inserire ?
Grazie mille!!! si piano piano faremo tutto
Ciao! Innanzitutto siete bravissimi ma volevo chiedere quanto potrebbe andare a costare un acquario marino (anche piccolo dato che non voglio inserire pesci come i pesci chirurgo che so che hanno bisogno di acquari grandi) grazie in anticipo ;)
dipende da molti fattori, in questa sezione del nostro sito ti potrai fare un idea www.aquascapinglab.com/category/marino/consigli-su-uso-materiale-tecnico-e-chimica-dellacqua/
Grazie! E già che ci sono vi chiedo un ultima cosa, se volessi inserire in acquario 6 guppy, 5 corydoras, 5 otocinclus e qualche lumachina (e magari qualche neon più avanti) quanti litri dovrebbe essere il suddetto acquario?
salve, perchè non raccogliete tutte le nozioni in un video con la pratica? mi spiego meglio, perchè non fate un reef o nanoreef passo passo dicendo cosa avete comprato e il perchè? magari fate anche i video aggiornamento o il timelapse giorno-notte come avete fatto con altri acquari di acqua dolce, verrebbe un capolavoro conoscendovi, siete fantastici
Grazie per il consiglio!!! si certo appena ne abbiamo la possibilità lo facciamo ovviamente
scusate io vorrei inziare ad allevare il pesce mandarino potreste fare un video sull'argomento ??
piano piano facciamo tutti i pesci.... rimani aggiornato sul nostro sito ufficiale www.aquascapinglab.com
+Aquascaping Lab grazie ...
podríais traducir al español
thank you but only in italiano and english!! :-)
