Micro fauna or mandrins ?
Daphbio brings some elements of answer
Oftenly reef aquarists are wondering : microfauna or mandarins ?
Difficult decision, tough choice, aquarium maturity, need for shelters and many subsidiary issues are pending.
But are we on the correct path ?
Although mandarins exert strong pressure on microfauna and meiofauna, also on the tiny plankton type Brachionus, invisible to the naked eye.
Can we conclude that this species of fish would be harmful for microfauna, meiofauna and zooplankton in the aquarium as many reef aquarists think?
Most reef aquarists agree that Mandarin will totally depopulate the whole micro fauna of the aquarium making impossible the existence for any form of micro-life.
Well we can assert this is less than proven…
Indeed, Daphbio have seen in cases where micro fauna, meiofauna is totally absent in aquariums. But often contrary to popular beliefs, there are no micro-fauna of predators, meiofauna, micro zooplankton in these aquariums.
In fact, where there are no fish, invertebrates, we have seen that there is often very little or not at all microfauna and zooplankton.
In aquarium with small delicate fish and even mandarins, a very small micro fauna can be nevertheless still present. Of course in very small quantities but nevertheless it is there.
Saying mandarins and small delicate fish can maintain microfauna would not be completely wrong.
We know the mandarins will ingest throughout their lives significant amounts of copepods, micro-worms, larvae Gammarus, amphipods, but also the eggs of the same micro-fauna.
These eggs often have a fairly rigid shell and once in the fish stomach, they do not necessarily all die. On the contrary, the stomach acids will perforate the shell and allow the larvae to hatch. The dispersal and colonization of the biotope done by rectal rejection.
Larvaes will feed on bacteria, enzymes, micro-plankton, decaying matter, which will ensure their survival.
These findings were made during multiple visits to reef aquarists, but also through the mails that we receive all year long from around the world.
National aquarium biologists, state researchers specialized in micro-crustaceans, explain microorganisms, pathogenic or not, use higher animals, fish and even certain times birds, for their survival and pervasion.
Do not hesitate to have the pleasure of ownig such a magnificent fish ; knowing that daphbio will help you to maintain your microfauna.
We advise you to add micro fauna twice a year to prevent its loss.
