Bitterling Breeding Guidelines

So, are you super excited to bring baby bitterlings into your aquarium? Well, then there are certain things that you must know about their breeding process. Bitterlings are highly known for their unusual and fascinating spawning mechanism.

In the wild, this bitterling Rhodeus species is a mussel-spawner. So, when you are breeding this species in your home aquarium, to mimic their natural habitat site, the tank must contain at least one unionid bivalve freshwater clam.

The females lay their eggs in the gills of a fresh, clear water mussel. The male fishes, which display brilliant colors during the breeding season, quickly follow the females and sprays their sperm in the gill cavity of bivalve freshwater mussels. And this further results in the fertilization of the eggs.

The eggs generally stay inside the mussel’s gill cavity for around 4 weeks. After hatching, the baby bitterlings remain within the clam itself for about 1-month. And after they grow a bit large to fend for themselves, they leave the freshwater mussels as active larvae.
