some shrimp question

[davescube]

This 2 days, 2 of my shrimps died..
I notice that they have been molting everyday but not all the shrimp of the same day of course..
I notice some shrimplet too
forgot to mention, it is cherry shrimp

anyway, my question is,
- is some of the shrimp may die when newly introduced to a new enviroment?

- what does molting indicate?
and calcium helps them in molting, am i right?

- is ammonia 1.0 ppm bad enough?

- is it possible that a tank will never cycle even in 1 year?

No, your shrimp should not be dieing because of a new home. Ammonia in your tank is weakening them. Shrimp won't tolerate any ammonia. You need to do a PWC to help lower that.
Molting means they are growing.

I agree that the ammonia is the issue. Its not uncommon for juvenile shrimp to molt frequently especially after a water change or a change in environment. I would do wc's to lower that ammonia to as close to 0 as possible and monitor it closely. Good luck!

Ammonia have been reading 1.0 this 2 weeks, didnt perform any large water change before.. 10% only usually..
maybe I should do a larger water change.. like 30% every week

Maybe do 10% every other day for a little while. Ammonia at 1ppm is kinda bad. Large water changes upset the shrimp too as the water conditions can dramatically change and stresses the shrimp. Younger shrimp are more tolorant of water conditions and changes than the adults. Maybe get some Biospira by Marineland to re-establish a bacterial balance to break down the ammonia or possibly add some purigen to the filtration to pull organics out. It's difficult to say, If you also have a pic of the tank itself, it might help to see what in the setup may need fixing or cleaning.

I thought I would add a bit more, from what I've learned and experienced over the years. My responses are in red.

Breeding is a good sign, but are the young surviving?

anyway, my question is,
- is some of the shrimp may die when newly introduced to a new enviroment?

When shrimp are shipped or moved to a new tank, they are stressed. Stress harms anything living. Shrimp are particularly vulnerable to stress. Low amounts of stress, over time, will drastically shorten the affected shrimp's live span. Higher amounts will kill them outright.

- what does molting indicate?
and calcium helps them in molting, am i right?

As stated, molting is how shrimp grow. Frequent molting is a sign of stress. Either from environmental toxins (metals, and other chemicals can be trapped in the discarded carapace), are eliminated from the animal via this mechanism.

- is ammonia 1.0 ppm bad enough?

Yes. If your shrimp have adversely suffered during their lives, this could be the proverbial 'straw' that broke them.

- is it possible that a tank will never cycle even in 1 year?

It is possible for a tank to become unhealthy. Either by removing the source of nitrates and ammonia that the bacteria need to survive, or by introducing a harmful agent that kills the bacteria.

I would recommend that you also test your water for other toxins, metals in particular, as they are extremely harmful to shrimp.

Good luck.

ammonia is a threat get rid by doing pwc every other day, an when settled at 0.25ppm or less 25% weekly will be fine.
