12L Nano Shrimp Tank “Blacksand” – Week 32

More than half a year has passed since I set up this nano shrimp tank. Although the shrimp are surviving they are not thriving, yet.

Checking The Water Quality Weekly

I’ve been checking the water quality weekly for this nano shrimp tank to make sure there isn’t any ammonia or nitrite and very low levels of nitrate that might harm the shrimps.

To be honest, I do skip this weekly tests sometimes.

So far, nothing indicates to me that the water quality might be bad for the shrimps. I do observe the shrimps’ “moulted skin” from time to time but have yet to find any dead shrimps in this tank. That’s a good thing.

Also, I rarely see any of the shrimps looking weak and not grazing at all. They all seem active all the time and while I can’t assume that everything is going well, I do hope they are are not sick or something like that.

Food And Algae

Up till now, I have this idea that feeding a variety of food is good for the shrimps. They include Hikari shrimp and crustacean food, algae tabs and BorneoWild baby shrimp food.

There are also algae in this tank on the tank walls, hardscape and etc.

While it may be a good idea, it isn’t working for this tank as the shrimps remained small compared to those (of the same batch) in my nano Iwagumi tank. They’ve been eating nothing but algae in that tank.

Could it be that I need to grow more algae in my nano shrimp tank?

Considering Alternative Food

I’ve seen some breeders feeding frozen bloodworms to their shrimps. Doesn’t look that hard at all except that I don’t know where to find them at the moment. Have never considered live or frozen food for my shrimps and fishes.

That might change if the situation doesn’t improve soon.

Another thought would be to feed my shrimps other brands of shrimp food. I’ll have to ask around and see what other breeders are feeding their Neocaridina shrimps, to be specific.

Water Parameters And Inducing Moulting

Then there’s also a theory that my tank water parameters may be too stable to induce moulting. If they don’t moult often enough, they can’t grow bigger and start breeding, possibly?

I do about 10-20% water change for this tank weekly and each time I will drip the water back in slowly. I’ve always been worried that I might shock the shrimps if I do a water change too quickly.

Perhaps I should do a big water change once in a while to induce moulting.

Where Does The Problem Lie?

If you have any experience in raising Neocaridina shrimps, I would love to hear any tips that you might have for my nano shrimp tank. Could it be the food I’m feeding them or could the water parameters play a part?

What say you?
