During this process, the male and female get into the classic &#8220;T&#8221;-position. The male is at the base and will release sperm, which the female will swallow.

Females have found a way to pass the sperm via their digestive system and fertilize the eggs.<\/p><p>Where the female will deposit the eggs, and how much, depends on the species. As dr. Ian Fuller describes, that some species have very sticky eggs, that are laid closely together in a clump. Other species lay less sticky eggs, more scattered around the tank. The latter usually inhabit slower moving rivers, where this is of less importance.<\/p><p>Corydoras aeneus for example lay their eggs all at once, in huge quantities.
