Sexual Dimorphism Males are more colourful and develop more-extended fins than females. Reproduction Bubble-nester. At the point of climax milt and a few eggs are released which the female proceeds to catch between pelvic fins and body.
The male then transfers them to his nest while the female recovers any that fell. The eggs hatch in hours, remaining in the nest for a further days until the yolk sac is fully-absorbed, while the male continues to collecting and return any that fall.
If threatened the entire nest may be moved elsewhere. Once the fry begin to swim freely the male will lose interest, but the adults do not usually eat their offspring. The specific name is derived from the coastal subdistrict of the same name in Samut Sakhon province, just south of Bangkok, where it was first discovered.
So-called due to its maze-like structure this organ allows the fish to breathe atmospheric air to a certain extent. References Kowasupat, C. Panijpan, P. Ruenwongsa, and N.
