Hump-backed limia
Livebearers · Easy

Breeding the hump-backed limia

Livebearer that breeds very easily in hard, alkaline water; keep several females per male. Gestation about 6-8 weeks; broods of up to 50. Adults eat fry, so move gravid females to their own tank. Warmer water may produce more females.

Full species page

Step by step

Pairing

One male with 3 females.

Breeding tank

Planted 60 L tank with hard water, floating plants and a breeding trap if needed.

What starts it

Warm 26-28 C water and good feeding.

Eggs and young

20-30 young (FishBase) to up to 50 (Seriously Fish) per brood, after about 6-8 weeks gestation.

Raising the fry

Feed crushed flake and baby brine shrimp; fry grow well in hard, warm water.

Common mistakes
  • Soft water
  • Not enough females
  • No cover for fry

    Heat the room or each tank · 22–26 °C

In total: 3 tanks, about 300 L of water. A litre of water weighs about 1 kg, so check that the floor and rack can take the weight.

Sizes are worked out from the breeding tank in the guide. Tanks fit a standard 120 cm rack when they can; bigger tanks go on their own stands.

Male or female

Males have a gonopodium, are slightly smaller and more colourful, and develop a hump along the back (fatty tissue); females are larger with a straight back.

Can I breed it in my tank?

  • Good for a first breeding project.

Day-by-day plan

Typical for livebearers

  1. 28 days beforePregnancy

    A dark 'gravid spot' grows behind the belly. Gestation is usually about 4 weeks.

  2. Day 0Birth

    Fry are born ready to swim. Thick plants or a breeding box keep them safe from adults.

  3. Day 0First food

    Feed crushed flake, baby brine shrimp or microworms 3–5 times a day.

  4. Day 28Sexing starts

    Males start to show color and a pointed anal fin. Separate them if you want to control lines.

  5. Day 90Adults

    Most livebearers are grown and can breed at about 3 months.

A general guide for this breeding type. Days change with temperature and species.

  • The female gave birth.
  • With no plants or breeding box, the adults ate most of the fry.
