12L Nano Shrimp Tank “Blacksand” – Week 4

New shipment of shrimps arrived at an LFS earlier than expected. Suffice to say, I happily brought 20 pieces home for my nano shrimp tank.

The Water Quality

Four weeks after setting up my nano shrimp tank, I’m happy to report that it has fully cycled. Zero ammonia, nitrite and nitrate had been achieved with the fishless cycling method.

All I had to do now was to maintain it until I add shrimps to the tank.

A thick coating of green algae had formed on the hardscape, substrate and tank walls by this time. In preparation, I scraped it off the tank walls and left the ones on the substrate and hardscape untouched for the shrimps.

The Water Parameters

In an attempt to create an ideal environment for the shrimps, I decided to raise the GH a bit. I used BorneoWild GH/KH+ to bring the TDS up to 200ppm and this gives me a GH of about 8°.

pH has been around 7.6 all the while using treated tap water and there isn’t a need to adjust it. I will continue monitoring the pH to make sure that everything is okay.

Even with a fan, the temperature of the tank water hovers around 27°C. It does go up a bit as it has been a hot month. This is less than ideal but it will have to do for now.

Acclimating And Adding The Shrimps

As mentioned earlier, an LFS brought in a new shipment of shrimps and I got all excited. I wasn’t expecting the shipment to arrive this early but I do know that I want to choose the best ones before it’s gone.

At the LFS, I handpicked 16 female shrimps which are already berried and another four which I think are male shrimps (not berried, no saddles and slender underbelly).

In all, I bought 20 Red Rili shrimps and brought them home.

The shrimps were acclimated using the drip method for about one hour as the water from the LFS tank were almost similar to the one in my tank in terms of pH and TDS. No need to prolong the acclimation period then.

I did an extra step of giving the shrimps a two-minute salt bath before adding them to my tank. This is a precaution against the Scutariella japonica parasites which is a common problem for Neocaridina shrimps.

Planned Weekly Maintenance

With the shrimps inside the tank, my focus will now be to feed them regularly and maintaining the water quality as well as parameters. I want them to not only survive in my tank but to also thrive.

I plan to do a 10-20% water change weekly. This is to prevent excess nutrients from building up and the increase in GH due to the frequent water top ups that I’m making up for evaporation.

As for feeding, a varied diet of shrimp food four times a week should suffice.

At the same time, I have increased the photoperiod from six hours to eight hours to encourage more algae to grow. This translates to more natural food for the shrimps.

Things To Consider

I am considering if I should put a nerite snail into this tank. It’s more for keeping the algae from growing out of control and to keep the biological load going. Nerite snails do poop a lot. What do you think?

  1. Another nicely done video that’s soothing to the ear and eye. Visually appealing.

    A new video, a new question.

    Would trying to grow the moss in way that’s a little similar to DSM work?

    You could put the driftwood with Xmas moss in a transparent container have a inch or two of water in it and seal the opening with a plastic wrap?

    But I’m afraid that the moss would melt when you put it back into the tank when the cycling is done.

    Cheers!

    1. Thank you once again. The Christmas moss on this wood was in fact grown using DSM a few weeks prior to tank set up. Just compare the videos/photos of it from setting up to the latest one and you’ll see how much it has grown. I’ve never trimmed it yet.

    1. Snails do poop a lot and in a nano tank, it might make a difference. That said, I know some shrimp breeders have snails in their shrimp tank to keep the bioload high so their tank has a bigger colony of beneficial bacteria and to clean leftover food.

      All snails reproduce but not all will overpopulate your tank. An example will be Nerite snails because their eggs need to be in brackish water to hatch. The downside to Nerite snails is that they’ll lay their eggs everywhere and it sticks to your tank glass, hardscape and etc. making it unsightly. Unless you’re lucky enough to get a male Nerite snail.

What say you?
