12L Nano Shrimp Tank “Blacksand” – Week 16

Almost zero adult shrimps left in my nano shrimp tank but the number of shrimplets I see in it gives me hope that the colony will thrive.

Algae Wall Recovery

Previously, algae on the tank walls have decreased. I was a little concerned that it might not be enough for the shrimps especially the shrimplets that are still growing.

Growing more algae is actually not that hard. I only had to create an imbalance in the tank. More light was needed so I increased the photoperiod to 10 hours daily and the algae started coating the tank walls again.

Excess nutrient in the form of fertilizers or over-feeding would also have helped to grow more algae but I chose not to go that route. Shrimps are sensitive and adding fertilizers that are not needed might put a strain on them.

My number one concern with over-feeding are pests that might find their way into the tank. For example, planaria. The bane of shrimp tank owners because they can be hard to get rid of.

So, be careful not to overdo it as it may invite unwanted algae and pests.

Adult Shrimps And The Weather

The weather last few weeks hasn’t been good for the tank inhabitants. It was so hot for a couple of days and it may have affected the shrimps in my tank. Sadly, I lost a couple of adult shrimps and there are less than a handful left.

Then again, it may not have been the weather that got the shrimps.

As much as I have tried my best to create a suitable environment for the adult shrimps, I think they have not gotten used to the tank parameters even after a long time.

They have been bred in an environment that might have been very much different from my nano shrimp tank. Well, certain things are beyond our control and we can only hope for the best.

The Surviving Shrimplets

Although some adult shrimps had perished, the shrimplets seem unaffected by the hot weather. I still see a lot of them crawling around and actively grazing. In fact, I do spot their moult once every few days.

I haven’t seen any dead shrimplets yet and counting the survivors are near impossible. A quick check tells me that there are more than 50 shrimplets in my tank.

This gives me hope that the colony will continue to grow.

Very soon, I can no longer call them shrimplets as they would have grown to adult shrimps and ready to mate. I do expect them to survive and thrive better as they were hatched and bred in this tank.

More And More Christmas Moss

The Christmas moss on the driftwood kept on growing and those on the driftwood is now very dense and pleasant to look at. In case you’re wondering, the moss was neither tied nor glued to the driftwood.

They had been chopped and then “painted” on the driftwood using a brush. Then, they were left to grow emersed for a few weeks before I set up this tank. I think it’s a nice method to grow moss on hardscapes.

There is a small drawback, though.

Some of the moss might not have attached themselves completely to the driftwood and will start to float away when placed in a tank full of water. That’s what happened to mine. The shrimps were guilty of uprooting them too.

For the free-floating moss, I just left them unattended in the tank and they usually gather at the filter inlet. And, because they are hardy, they still continue to grow there. I’ll probably harvest them for another setup later.

A Side Project

I’m starting another tank for a side project and some of the shrimps might be transferred there. As to what the side project is for, I can’t give much detail until it is confirmed. Subscribe to my blog if you want to know what it is later.

  1. Following your video one by one.

    It’s sad that the adult shrimp are slowly passing on, it might be as you mention.

    They grow up in a different place with a different set of parameters.

    But their offspring are locally born and would surely do better!

    All the best.

    1. In fact, their offsprings are doing better in this tank. I hope to see them making their very own offsprings in this tank too.
