Hej,

Jeg kom hjem og pludselig kom der en masse hvide tråde ud fra min søpølse. Er der nogen der har set noget lignede og kan forklare dette?

det er vist en forsvars-mekanisme. og potentielt dårligt!!!

"Many cucumbers in this group may eject quantities of sticky filamentous threads (Cuvierian tubules) or expel their internal organs to defend themselves, and some can grow quite large."


"Some tropical bottom-feeding sea cucumber species have defensive structures, called Cuvierian tubules or Cuvierian organs. If these animals are stressed, they may expel these tubules from the anus during a partial evisceration. The Cuvierian tubules are sticky and, in some species, contain a vertebrate-specific toxin called holothurin. In nature, this reaction probably just distracts, irritates, and sickens a potential predator. It is unlikely that it would be lethal. However, the predator is probably deterred from that particular cucumber, which will live to regenerate its lost parts. In the enclosed volume of an aquarium, however, the evisceration response, followed by the holothurin liberation, may result in contamination that could rapidly kill all the fishes and perhaps some of the invertebrates."

Det lyder da ikke for godt. Hvad bør man gøre i det tilfælde - skaffe sig af med søpølsen?

Jamen skidt.... jeg kan ikke lige finde den lige nu. Den smuttede ind under stensætningen efterfølgende.

Skal jeg splitte baljen ad for at finde den for at undgå dette "contamination" eller bare en stor gang vandsplit. Her morgen efter er der ikke lige noget spor af det. Fik suget trådene op (de fleste af dem) efterfølgende.

Hvis der ikke er sket noget endnu, så tror jeg bare at du skal tage det roligt. Men et vandskifte forværer ihvertfald ikke situationen.

Lavede her til morgen et 10% vandskift. Dette var lavet ifm at jeg efter en flytning af akvariet til en ny lejlighed, har fået et alge boom. Så det skulle ske alligevel.

Satser på at der ikke sker mere, men det så meget syligt ud med de tråde faktisk.

sug trådene op hvis du kan, smid noget kul i og lav vandskift.

ellers hold godt øje med pølsen, for den kan jo være tæt på at stile træskoene..

håber der ikke sker noget
