Hvor meget og hvor ofte skal de fodres? har frostterninger som jeg fodre med en dag. Samt noritang og flagefoder en gang om dagen

Just so people don't get confused, may I underscore the differences in the term "Nutrients" and the various ways corals and other animals get these substances
1.Nutrients that are the products of photosynthesis. The common symbiotic relationships found with animals and photosynthetic algae and bacteria are an adaptation to this "low nutrient" water. This is typically high carbon content stuff, and a source of metabolic quick energy and much is lost in the production of mucus (which then feeds other things)
2.Dissolved nutrients; these are things that we measure like NO3-N, NH4, PO4, etc. On the reef, most N is ammonia as nitrate is so low. The levels are very very low. Not so in most tanks, even when measurably low by test kits. If reef waters were higher in dissolved nutrients (excluding some turbid areas), then you would have proliferation of phytoplankton and algae. Corals are successful where dissolved nutrients are low because they both feed heavily on 3 (below) and have the advantage of the phostynthetic symbionts. When nurient levels get high, coral reefs start to lose diversity, eventually disappearing. However, where dissolved nutrients are higher, prey is also high though light is low. In such cases, corals still exist, but they don't form reefs and they are mostly if not totally asymbiotic.
3.Nutrients derived from prey capture; this is what we are lacking and where corals get such a large percentage of their nutrition. Capturing food. Particulate matter (detritus, mucus, etc.) is dead and a valuable food source. It is less desirable than living plankton other prey organisms because it gets acted on quickly by decomposition which tends to increase dissolved nutrients. However, if the dead particulate matter is not too much (like when sedimentation from storms,e tc. occurs) and remains in the water column, the many mouths will eagerly consume and convert to biomass before degradation occurs. It is also typically high carbon content, but is enriched by bacterial biomass that grows on its surface Live prey is considered "nutrients" in that its consituent matter is part of total organic stores, but does not degrade water quality.
