12L Nano Shrimp Tank “Blacksand” – Week 40

Lower light intensity seems to help for the moss that was turning brown but it also led to lesser green algae in this nano shrimp tank.

Getting Less Algae

When I modified the LED lights with inline dimmers for my other tanks, I also modified the light for this tank. Not that it needed the modification but since I’m already doing it, why not do for all of them, right?

I lowered the light intensity for this tank by half just to see what happens.

After a while, the algae on the tank wall began to decrease. It was more apparent on the wood where I can usually spot algae but it looks like it’s no longer there.

Lowering the light intensity helps reduce algae but it might not be a good idea for a shrimp tank. The shrimps really could use all those algae as their staple food.

Giving The Moss Some Help

Some parts of the moss are turning brown and I’m not exactly sure what’s causing it. I had the impression that the moss had grown higher and nearer to the light and that caused it to turn brown.

After lowering the light intensity, it seems to help a bit as I noticed the moss is starting to turn green again. It might just be a coincidence, though. The moss might have grown too thick and the ones underneath are dying.

I have no plans to trim the moss and will just wait and see what happens.

Red Rili Colour

I fell in love with the Red Rili shrimps because of their unique colour and pattern. I still think they are one of the most beautiful Neocaridina shrimps that I have seen so far.

Sadly, some of the shrimps in my tank are losing their colour or should I say, they were born without the unique colour and pattern that I love. I do know that it can happen if their genes are not strong enough, or so they say.

I’m not overly concerned regarding this. Those that kept and bred shrimps will usually separate the shrimps that do not have the traits (colour and pattern in this instance) like their parents.

As for me, I’m not focused on breeding them for their colour anyway.

The Number Of Shrimps Left

Another thing that makes me feel discouraged is the number of shrimps left in this tank. Was it the water parameters or quality? Or was it the type of filter I’m using? Could it be the food that I’m feeding them?

Last I checked, there’s about 20 of them left.

It’s kind of a hit-and-miss with these shrimps. Shrimps in one of my other tanks are breeding quite well actually. It’s like, if you don’t focus on them too much, they’ll survive better.

I may want to add another batch of shrimps just to reinvigorate the numbers.

What I’ve Learned So Far

This shrimp tank has thought me a lot of things. If I had to choose, the most important to me would be understanding water quality and parameters. What’s the most important thing you have learned from your tank?

What say you?
