Issue with Keeping Shrimp

So I am getting a little frustrated and light in the wallet from trying to keep shrimp. So far I have tried (2) cleaner and (2) Fire Shrimp. All have lasted about a month and then mysteriously die. One was directly related to a bad molt. All of my parameters are perfectly in line (tested last night). The only thing that is a little high is my SG 1.025 (I have always keeped it at this level). Temperature is always consistent at 78 degress (chiller). I cannot figure out what I am doing wrong, I drip acclimate and feel I am very careful. I have had no issue keeping anything else alive and thriving. I perform 10% water changes each week and the only other things in the tank (other then coral) are (2) Clowns, (2) Blue Legged Hermits, and (4) Snails.

Any input would be greatly appreciated!

 

You have everything right except possibly iodine. Shrimp need iodine to successfully molt.

 

How often do you top off? shrimp are one of the most sensitive animals to salinity swings.

 

Do you have all 4 at once or one after another? 29 gallon may be a little crowded for all 4, I think.

 

Actually, iodine is toxic, and shrimp molt to get rid of it. If there's nearly any iodine in the salt mix, you don't need to add it. It's in the same family of elements as chlorine, flourine, and bromine, two of which I personally know to be used specifically to kill nearly anything living.

If you do add it, you should have a test kit, as always.

 

I use Instant Ocean Reef Crystals. The only add I use is:

Brightwell Aquatics Alkalin8.3-P - Dry pH Buffer & Alkalinity(KH)-Builder 500g / 1.1 lbs.

I only need to add this about once a week to maintain my PH around 8.30 - 8.34. I have a ATO unit that add water automatically so it should not be a huge influx of fresh water.

I have only added one shrimp at a time. I never had more then 1 at any given time.
