12L Nano Shrimp Tank “Blacksand” – Week 12

I’m starting to feel that maintaining a nano shrimp tank is not that hard after all. Here’s what it looks like after 12 weeks and counting.

Stable Water Parameters

You know how they say that a bigger tank has more water volume and that equates to a more stable water parameters? That’s true but I do find that it is still possible with a nano tank.

I guess if you don’t slack with the regular tank maintenance and monitor the water quality as well as parameters closely, it can actually be done.

Slightly harder than a bigger tank but not impossible.

As for this nano shrimp tank, the water quality has been fantastic and parameters have not deviated that much over the past few weeks even with regular top ups for evaporation. Only 10-20% water change is needed weekly.

Natural Food For The Shrimps

Anyone who is new to keeping shrimp will probably hate looking at algae on their tank walls. I knew I did when I first started. So much so that I kept scraping it off weekly.

I realise now that it is not a good idea if you want the shrimp to have a higher survival rate. They need those algae to survive and thrive.

Adult Shrimps Survival

Even with good water quality, stable parameters and green algae walls, there were shrimps that died in my nano shrimp tank. It’s mostly the adult shrimp that didn’t make it.

That said, it’s not as much as my previous tank setup.

I haven’t been able to find the reason why they died and the only assumption or guess I have is that they are either already very old and dying or they are just not used to the tank water parameters.

Shrimplets To Colonize The Tank

No shrimplets death were spotted during this time. They are still tiny and even if they did die in the tank, I probably wouldn’t have spotted it. They are still around and most of them looked healthy.

I believe that there are more than three or four times the number of shrimplets compared to the adult shrimps. Can’t be sure as they are still small and it’s impossible to spot all of them in the tank.

My hope is that they will continue to grow in my tankĀ  (since they are born and bred here) and breed in it. There’s a problem though. Some of the doesn’t resemble Red Rili shrimps in terms of quality and I may have to separate them.

Starting Another Tank

When budget permits, I would like to set up another small tank to place all of the shrimps that doesn’t make the cut, so to speak. Other alternatives would probably be to give them away or sell it to willing buyers.

  1. This does seem to be an issue with most shrimp from what I am learning, they don’t always breed true to form. I guess this is where the “selective” breeding comes in to play. As with most things you may have to be quite hard on the choice when selecting only the best to keep as a breeding colony… maybe over many generations, they may breed more true to type?

    Keep up the great work!!

    1. That’s right. If I understood it correctly, most of the Neocaridina species doesn’t “breed true”. Which means to say that they don’t resemble their parents when young. Will take some time for them to show their true colours.

      For these batch of Red Rili shrimps that I got, it may have interbred with another variety of Neocaridina species. The LFS had put them together with a batch of Golden Back Yellow shrimps, if I remembered correctly.

What say you?
