12L Nano Shrimp Tank “Blacksand” – Week 8

Eight weeks on and I’m pleased to see shrimplets (as well as algae) all over my nano shrimp tank. They look healthy and are growing well.

Christmas Moss Growth

The water quality and parameters have been fantastic. Still no ammonia, nitrite and nitrate for the past few weeks. It kind of worried me that there’s almost no nitrate and if it will be detrimental to the Christmas moss.

Nonetheless, I observed that the Christmas moss are still green and they are growing well. The sad part is that the shrimps had pulled some of the moss off the driftwood after their first day in the tank.

I hope that the Christmas moss will continue to grow nicely.

Feeding The Shrimps

Apart from eating algae and biofilm that they find in the tank, the shrimps are also fed four times a week. I believe that feeding the shrimps a variety of food will keep them strong and healthy.

In case you’re curious, I am currently feeding the shrimps the following food.

  1. Hikari Tropical Shrimp Cuisine
  2. Hikari Tropical Crab Cuisine
  3. Hikari Tropical Mini Algae Wafers
  4. BorneoWild Bebi

The Hikari food comes in small packets and is relatively cheap and you can consider feeding your shrimps this food. Although the amount of food in each packet is small, it is more than enough for a small colony of shrimps.

As for the BorneoWild food, it’s a little more expensive but does come recommended by other shrimpkeepers. They also have a wide variety of food for different types of shrimps.

The First Batch Of Shrimplets

At about three weeks or so in the tank, all of the berried shrimps are no longer carrying their eggs. I’d have to assume that most of the eggs have already hatched judging by the numbers of shrimplets spotted.

I do see their moulted shell floating around once in a while. I take it as a good sign that they are growing well. I’m also surprised to see that some of them have developed their red colour so quickly but it isn’t very pronounced yet.

The odd thing is I do see shrimplets that are not red in colour. Some look bluish and even black. It’s probably because the shrimplets are reverting back to their wild colours. Another reason could be that the female shrimps had cross-bred with male shrimps of a different variety before I bought them at the LFS.

I may want to cull these offsprings that do not resemble the Red Rili.

Green Algae Wall

One of the mistakes I did with my previous shrimp tank setup last time was to constantly remove all traces of algae that I find on the tank walls. Had all the tank walls scraped until it’s nice to look at but the shrimps kept dying.

I realised that a shrimp tank should not be treated like a planted tank and algae are essential for the shrimps’ survival and growth. The green algae are natural staple food the shrimps and they can be seen “scaling” the walls to pick on the algae. It’s the shrimplets that are mostly seen eating the algae off the tank walls probably because they are smaller and it is easier for them to do so.

So now, I scrape the algae off the front tank wall only.

Waiting For The Next Batch

Since the shrimps are surviving well in this tank setup, I would like to see if they are able to thrive in it. I’m hoping that the female shrimps will be berried again if all goes well.

Maybe, I should add more male shrimps to this tank?
