Breeding the lesser siren
Rarely bred in captivity (one documented success, Reinhard, Voitel & Kupfer 2013). Breeds roughly November-May; the male defends a nest cavity, the female lays eggs in it, and the male guards and aerates the eggs; larvae develop in about 35 days.
Step by step
Not practical.
Large shallow tank with plants.
Unknown.
About 12-300 eggs per clutch, possibly several clutches a year; hatchlings about 1.1 cm.
Larvae need tiny live foods.
- Fish tankmates
- Poor water
- Wild-caught stock
Male or female
Males are on average about 14% larger than females and have enlarged jaw (masseter) muscles, so their heads look bigger.
Can I breed it in my tank?
- Hard: for experienced breeders.

Set up a virtual breeding tank and see what would likely happen.
- Without live or frozen food the parents aren't in breeding condition.
