Blue Velvet Shrimp Dying: 11 Suspects Of Their Demise

blue velvet shrimp dying - causes

Your Blue Velvet shrimp dying is a very unfortunate sight, no matter if you are a breeder or an aquarium hobbyist. 

Let’s talk about several suspects of their demise. 

1. Overfeeding 

It seems to me like your Blue Velvet shrimp are getting the all-you-can-eat buffet a bit too often. 

While it is okay to feed them small amounts 5 times a week, overfeeding (giving them big chunks too often) can lead to some serious health problems and even death. 

It is not that their bellies explode from too much food, it is all that excess food that starts to break down and create harmful chemicals in the water, resulting in a thick biofilm on the surface. 

2. Overcrowding

Overcrowding a.k.a overpopulation is when you have too many shrimp or other fish in the tank. Things get pretty cramped and stressful for all of them. 

They can’t move properly and finding proper hiding places becomes practically impossible. Everyone is in everyone’s business here!

3. Tank Issues

If your tank is too small, your blue beauties won’t have enough room to roam around and find food. 

Moving on to the glue that holds your tank together. Low-quality silicone can release harmful chemicals into the water and put your shrimp in danger. 

Some dyes and chemicals found in the tank can be toxic to your shrimp. This usually happens when you buy second hand tanks that come with their own set of flaws. 

4. Water Quality

I can not stress enough how important water quality for Blue Velvet shrimp is. If the water quality is not up to snuff, it can cause all sorts of health problems that can put your shrimp in lethal danger.

For example, high concentrations of ammonia can cause ammonia poisoning in all tank species, including shrimp. Besides that, if the pH level in the water changes suddenly, it can be a shock to their system. 

But, that is not all, chlorine and hard water can also be the silent killers of your shrimp! They can prevent the shrimp from molting properly which can lead to death. 

5. Uncycled Tank

An uncycled tank can be a real demise for your Blue Velvet shrimp. If the tank hasn’t had time to mature and establish a healthy balance of beneficial bacteria, it can lead to all sorts of health problems that can result in your shrimp and other fish dying. 

Besides high levels of ammonia, nitrite levels can also be a huge problem. Nitrites can harm the shrimp’s body and metabolism, making them weak. 

Additionally, compounds such as nitrates can stress out your blue beauties and affect their health. 

6. Sudden Water Changes

Water changes can be a lifesaver for your Blue Velvet shrimp, but if they are done too suddenly or too fast, they can also be a death sentence. 

It is like a shock for the shrimp’s metabolism.

They don’t like sudden temperature changes and they are super-sensitive to water quality. 

7. Fast Acclimation

If you have just changed your tank water, your shrimp need time to acclimate to it. The problem occurs during sudden water change when Blue Velvets do not have enough time to acclimate properly to their new environment. 

That said, water change should be done gradually to give them enough time to adjust to the transition. 

8. Failed Molts

Sometimes things can go wrong and lead to failed molts. 

A failed molt can happen when this little shrimp is unable to shed its old shell and form a new one. This can be caused by stress due to aggressive tank mates, poor water conditions, or a diet insufficient of calcium and other minerals. 

So, when molting goes wrong, you may notice a white ring around the shrimp where the head meets the body. It is often called the “white ring of death” and it makes it difficult for the shrimp to break out of its old shell, leading to a painful death.

9. Toxic Plants

Toxic plants.. More like toxic terrors for your Blue Velvet shrimp! 

Some plants such as Hygro balsamica, release harmful chemicals into the water that can poison your shrimp. 

Additionally, some commercial aquarium plants are treated with pesticides, but these chemicals can kill your blue beauties. 

10. Tank Mates 

Blue Velvet can be pretty picky when it comes to who they share their tank with. Due to the fact that they are a peaceful species, they are often bullied by more aggressive tank mates. 

Such tank mates prey on the poor little shrimp, waiting for a moment to munch on them! Imagine how stressful that makes their life! 

Besides dying from stress, your shrimp can become a yummy snack to an aggressive fish such as a silvertip tetra! 

11. Shrimp Source 

Shopping for Blue Velvet shrimp can be a lot of fun, but not all sellers and breeders are reliable. Bad ones can lead to a whole tank of trouble!

Some irresponsible breeders raise their shrimp in an unhealthy or unsanitary environment where they can carry bacteria, viral diseases or parasites that can spread to your tank and harm your other shrimp. You know what this means? Shrimp demise!
