Methods to know when the tank is prepared for shrimp?

  1. When it’s fully cycled and stable. Adding any shrimp before that will likely result in a very poor outcome.

  2. I would highly recommend getting a TDS pen and test the tank water for Today Dissolved Solids.

    Then a API Master Freshwater Test Kit, and with that, test for ph, Ammonia, Nitrites and Nitrates.

    Finally, an API GH/KH Test Kit to test for General Hardness and Carbonate Hardness.

    Good luck!

  3. Based on the parameters you shared, your tank is ready for neocardina shrimp. Not any other.

    Add floating plants like red root floater or frogbit. They will absorb extra nitrate and also naturally populate microscopic fauna around their roots that will be free food for your fry. So your trip won’t see any causalities. Just make sure you have smart lights installed so that plants get their required light in your absence.

  4. In terms of a cycle, a tank can be ready in as little as 24-48 hours depending on how you cycled it. Some hobbyists will do the cycling the old fashioned way and let the tank idle for months with just rotting food, but with seeded media and excellent bacteria colony starters such as fritz turbostart 700 you can get this done really quickly.

    That being said to address your question, you are looking for two things:

    – How quickly your tank can process 1 ppm of Ammonia in 24 hours. I would recommend the sure fire method is to dose the tank with liquid ammonia drops up to 1-2ppm and track the time, but with fish in the tank this isn’t an option. So second best option, if nitrates are detectable in the water, you can feed little and sparingly to ensure the cycle is stable over the next 1-2 weeks with the shrimp.

    – The second thing you are looking for is ensuring your tank’s Ph, Kh and Gh ranges are correct for the type of shrimp you are looking to introduce.

    If both those two items are checked off you can add shrimp.

  5. Even past just the nitrogen cycle id bump up the hours your light is on and get some algae growth.

  6. You wanted an aged tank. A lot of microscopic activity happens outside the filter. For a 10 gallon I would be more careful because spikes in parms happen faster and are more extreme due to small water volume.

    Great job planning and patience will pay off. 😀

    It looks like your plants might need more light. My experience is if you can look directly at light bulb without it being uncomfortable. It’s probably not bright enough for a planted tank. Yes make fun of my comment.

    I have good results with these 2 links.


  7. Good indicators are plant growth and algae growth. Algae is ugly, but it’s part of the ecosystem, and shrimp love it. If you have a thriving colony, they’ll do the job of keeping it under control.

  8. I’m assuming you’re going for neos. But get salty shrimp gh kh, test for gh and kh with a kit (I use fluval). My tanks are usually ready after 7 days with Seachem stability (own crs and neos with blue bolts next). Check for ammonia, once that is 0 (with another day testing) I’ll acclimate shrimp via 1drop/2s and toss them in.

  9. The shrimps will tell you, they know, they know

  10. Is that their 21 gallon?

  11. I love that tank! I’m obsessed with shallow tanks! What size is that one?

  12. ez, when the cycle is finished
