The Feed used :-

  • Wordley Tropical Fish Flake Food (Morning Feed Light)
  • Zeigler Premium Shrimp Grower Feed (Night Feed)
  • Bloodworms (Once a week) Seems to promote breeding
  • Fresh/Frozen Vegetables- they really like green peas (5 times a week)

Acclimating :-

  1. Float your unopened in the water that they will introduced to adjust the temperature of the shipping water slowly
  2. Air line/stone
  3. Open bag and insert airline or pour into a container with airline
  4. Add tank water to adjust them to your PH *** Add water very slowly to your crayfish, don’t add enough at once to cover the crayfish completely. This acclimates their gill back to being submerged.
  5. Repeat #4 every 5-10 mins till the crayfish is covered
  6. Net them out of the water and add them to your tank. (DO NOT ADD SHIPPING WATER TO YOUR SYSTEM)

  • Cycling your tank: I know you hear this all the time but it is very important to have your tank cycled before introducing juvenile red claw. They are very sensitive to nitrate; I have seen them die within 10 hours at 5ppm nitrate.
  • Hides: You will need appropriate size hides in your tanks, 3 inch PVC for adults. You can use a verity of hides including PVC and rock caves. They feel comfortable in sung areas with only 1(one) opening. We recommend 2 hides per crayfish.
  • Tank Mates: Slow moving fish maybe come food; I have seen adult red claws catch tilapia in cooler water temp when the tilapia become sluggish.
