Blue Coral Banded Shrimp or Stenopus tenuirostris

Blue Coral Banded Shrimp or Stenopus tenuirostris

Welcome to a breeding experience. A success or a failure? I would say an apprenticeship. So I will explain step by step how to do it.

 Determine gender

To identify the female, very simple. Either she has eggs under her tail, a beautiful purplish blue, or we see the next spawn in her head. During the molt of the female, the eggs move from the head to the tail. Even in the head, the eggs have this purplish blue color. Be very careful: If you are not sure of the sex, never put more than 2 shrimps together. If a couple forms, in a few minutes the couple will kill the others shrimps.


My system consists of 15*5 gallons aquariums and a 40 gallons sump. The system is 4 stages, the sump at the bottom, and 3 stages of 5 aquariums. The pump send the water in the top 5 aquariums and each aquarium pours into the aquarium below. The lowest row of aquariums pour water into the sump. The sump is filled with live rock as well as each aquarium. The rock was sterilized and returned colonized only with the copepods I chose and nothing else. The light is the natural daylight. Every evening, the pump stops at 8 p.m. and all the lights in the room turn off at the same time. The phytoplankton cultures are in the same room. The pump is back at 4 am.

Larvae collecting

The advantage of isolating the couple in their own 5 gallons aquarium is that I can effortlessly remove the female from the system a few days before hatching. The female is placed in a plastic bowl with a small live rock for filtration and an air pump. Hatching occurs in the dark. Starting at 8 p.m., I check every 30 minutes for hatching by bringing a flashlight to the side of the bowl. The larvae are attracted to light. As soon as this phenomenon occurs, I put the female with the male, remove the small living stone and I only have to remove the larvae from the water. So I collect 100% of the larvae.

Breeding system

I really hesitated. Since this is my first time with this species and since there is not really any information on the web, I hesitated on the first system to use. 5 gallon aquarium, vertical kreisel, horizontal kreisel, others systems…

I opted for the vertical kreisel. A 10 gallon system with 24/7 lighting. The water goes around in circles continuously. The movement of the water is weak enough, just enough for the water to spin.

Daily maintenance

Every day, I siphon the deposit that forms at the base of the kreisel as well as the filter. Trash is inspected and larvae that have been mistakenly sucked are put back into the system.


Unfortunately I only had time to try 3 times. I lost the breeding pair when I redid the system.The best test was 15 days.

I will try again with this species if I can find a new breeding pair.
