Riba klaun - jajašca / Clownfish eggs / Amphiprion clarkii

Danas smo u akvariju opazili oplođena jajašca ribe klauna (Amphiprion clarkii). Nadamo se da ćemo drugi tjedan dobiti i ličinke. Razmnožavanje ribe klaun u prirodi, pa tako i u akvariju, odvija se tijekom cijele godine. Mrijest započinje tijekom punog mjeseca i uglavnom ujutro. Prije mrijesta mužjak gradi gnijezdo koji se u pravilu uvijek nalazi blizu vlasulje, kako bi i jaja imala zaštitu njezinih lovki. Mužjaci se potom udvaraju ženkama šireći peraje, grizući i naganjajući ih. Ženka započinje parenje polaganjem velikih narančastih jaja u gnijezdo, kojih može biti od 100 do 1000, ovisno o starosti ribe. Mužjak ih oplođuje, te se jaja pričvršćuju za podlogu tankim nitima. O jajima se prvenstveno brinu mužjaci, redovito ih hladeći svojim perajama i čisteći ih od oštećenih jaja i gljivica. Nakon 6-8 dana izvaljuju se ličinke.

Today we noticed fertilised eggs of Clownfish in our aquarium. We hope to get larvae next week. Namely, the spawning of Clownfish in nature as well as in aquaria takes place throughout the year. Spawning begins during a full moon and mostly in the morning. Before spawning, the male builds a nest, usually close to an anemone, so that the eggs will also be protected by the anemone’s tentacles. Males then court females by spreading their fins, biting and chasing them. The female begins mating by laying large orange eggs in the nest which can number from 100 to 1000 depending on the age of the fish. The male fertilises them and attaches them to the underlying surface with thin threads. The eggs are primarily taken care of by the males which cool them regularly with their fins and remove damaged eggs and fungi. After 6-8 days, the larvae hatch.
