Step by step

Pairing

One male and 2 females in a large tank with hides.

Breeding tank

Large tank with caves and sand; separate female when berried.

What starts it

Seasonal temperature changes and good feeding.

Eggs and young

One 9.6 cm wild female carried 74 eggs, each about 3 x 2 mm.

Raising the fry

Juveniles are tiny crayfish; feed meaty foods and keep separate to prevent cannibalism.

Common mistakes
  • Mixing males
  • Too little cover
  • Poor water quality

A plan from the breeding guide and an adult size of 12 cm. Tank shape is a standard 2 : 1 : 1.2 box, at least 6 adult lengths long. Check each step in the guide above.

Setup blueprint

Business setup

A rack of breeding and grow-out tanks.

The breeding guide gives no tank size for the boesemani crayfish yet, so a business layout can't be drawn.

Male or female

Adult males have a soft, pale yellow or white patch (decalcified swelling) on the lower edge of the claws; females lack it. Young males resemble females until it develops (at about 8 cm total length).

Can I breed it in my tank?

  • Good for a first breeding project.

  3. Day 30Growing

    Keep a sponge on the filter intake. Feed powdered shrimp food a little at a time.

  4. Day 90Adults

    They can breed themselves at about 3 months.

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