Het is inderdaan al weer even geleden.
Kom maar op met die update :mrgreen:

Ik heb niet gereageerd, maar volg dit allemaal wel.

Benieuwd naar je update :wink:

Na een lange periode in een andere bak laten acclamatieseren met beetjes water van mijn aquarium toe te voegen aan de spongen bak. En de juiste zweef algen te blijven voeren zijn ze nu terug geplaatst en doen het opmerkelijk goed. Van de 7 is er 1 nog wat aan de blanken kant maar de rest zijn mooi licht groen. Dus ja gaat tot zover nog goed...Maar makelijk is het niet.
Ik zal later weer een filmpje plaatsen.

Hoop dat ze het weer in deze bak hoed houden. Maar verwacht het wel. Ook een grotere stromingspomp bij gezet. Was volgens specialisten nodig.
Zie ondersyaand het Filmpje.

Erg gaaf om te zien dat ze nog leven en het goed lijken te doen.
Ik ben erg benieuwd welke verzorging jij ze geeft. Aantal keren per dag voeren, soort voer/zweefalg, waterwaarden etc.

Pfoe, dit heeft wel wat toewijding nodig hoor.
Hieronder wat interessante info (sorry voor de spam)
Asexual
Sponges have three asexual methods of reproduction: after fragmentation; by budding; and by producing gemmules. Fragments of sponges may be detached by currents or waves. They use the mobility of their pinacocytes and choanocytes and reshaping of the mesohyl to re-attach themselves to a suitable surface and then rebuild themselves as small but functional sponges over the course of several days. The same capabilities enable sponges that have been squeezed through a fine cloth to regenerate.[51] A sponge fragment can only regenerate if it contains both collencytes to produce mesohyl and archeocytes to produce all the other cell types.[41] A very few species reproduce by budding.[52]

Gemmules are "survival pods" which a few marine sponges and many freshwater species produce by the thousands when dying and which some, mainly freshwater species, regularly produce in autumn. Spongocytes make gemmules by wrapping shells of spongin, often reinforced with spicules, round clusters of archeocytes that are full of nutrients.[53] Freshwater gemmules may also include phytosynthesizing symbionts.[54] The gemmules then become dormant, and in this state can survive cold, drying out, lack of oxygen and extreme variations in salinity.[28] Freshwater gemmules often do not revive until the temperature drops, stays cold for a few months and then reaches a near-"normal" level.[54] When a gemmule germinates, the archeocytes round the outside of the cluster transform into pinacocytes, a membrane over a pore in the shell bursts, the cluster of cells slowly emerges, and most of the remaining archeocytes transform into other cell types needed to make a functioning sponge. Gemmules from the same species but different individuals can join forces to form one sponge.[55] Some gemmules are retained within the parent sponge, and in spring it can be difficult to tell whether an old sponge has revived or been "recolonized" by its own gemmules.[54]

Sexual
Most sponges are hermaphrodites (function as both sexes simultaneously), although sponges have no gonads (reproductive organs). Sperm are produced by choanocytes or entire choanocyte chambers that sink into the mesohyl and form spermatic cysts while eggs are formed by transformation of archeocytes, or of choanocytes in some species. Each egg generally acquires a yolk by consuming "nurse cells". During spawning, sperm burst out of their cysts and are expelled via the osculum. If they contact another sponge of the same species, the water flow carries them to choanocytes that engulf them but, instead of digesting them, metamorphose to an ameboid form and carry the sperm through the mesohyl to eggs, which in most cases engulf the carrier and its cargo.[56]

A few species release fertilized eggs into the water, but most retain the eggs until they hatch. There are four types of larvae, but all are balls of cells with an outer layer of cells whose flagellae or cilia enable the larvae to move. After swimming for a few days the larvae sink and crawl until they find a place to settle. Most of the cells transform into archeocytes and then into the types appropriate for their locations in a miniature adult sponge.[56]

Glass sponge embryos start by dividing into separate cells, but once 32 cells have formed they rapidly transform into larvae that externally are ovoid with a band of cilia round the middle that they use for movement, but internally have the typical glass sponge structure of spicules with a cobweb-like main syncitium draped around and between them and choanosyncytia with multiple collar bodies in the center. The larvae then leave their parents' bodies.[57]

Life cycle
Sponges in temperate regions live for at most a few years, but some tropical species and perhaps some deep-ocean ones may live for 200 years or more. Some calcified demosponges grow by only 0.2 mm (0.0079 in) per year and, if that rate is constant, specimens 1 m (3.3 ft) wide must be about 5,000 years old. Some sponges start sexual reproduction when only a few weeks old, while others wait until they are several years old.[28]

Ja lok bedankt voor je spam had ook het een en ander gevonden haaa.
Ik heb ze ondertussen maar bij mn pa in de bak gedaan ! Maar gaat er erg goed.

Heb de bak anders ingedeeld en mn sponzen weer bij mn vader in dw vmbak zolang ondergebracht, daat deden ze het toen ook erg goed. Door het voeren kleeg ik last van groenalg.
Maar mn tanganyika mosselen vinden die sporen wel lekker om te eten trouwens.
Eerst laat ik de slakken het alg weer ooeten dan plaats ik ze weer terug einde van de maand.
