How do you breed climbing perches?

Climbing perch (Anabas testudineus) are labyrinth fishes, and their breeding is similar to that of such well-known relatives as gouramis and Betta splendens, except that the climbing perch does not build or use a bubble nest and the male fish does not guard the eggs.

Females are broader across the middle (especially when viewed from above) than males. Some articles say the male also has more of a "knife-edged" anal fin (more pointed?) than females.

You will need to place the pair in a large aquarium containing a lot of floating plants. Again, their spawning is like that of many other labyrinth fishes, but with no bubble nest and no parental care. The eggs will float to the surface of the water and remain floating as the embryos develop. After spawning, the adult fish should be removed from the tank. I've found one source that says they do not eat their eggs, and a few others that say they eat their eggs, so I think it's the better part of wisdom to remove them as soon as the eggs are laid.

The young will hatch in around 3-5 days. Like other anabantoid (labyrinth fish) larvae, they are tiny at first, so once they have absorbed their yolk sacs, they will need the very small fry foods until they are large enough to eat baby brine shrimp and similar-sized foods.
