i know iodine can help keep shrimp healthy and promote growth and molting.
is iodine really needed and should i be adding it. additionally how much and how often, and will it hurt any other tank fauna. just curious as it doesnt seem my shrimp molt often, the adults almost never molt and the smaller shrimp molt rarely which to me points to a slowed growth.

That's new to me - I have 4 amano shrimp in my community tank and they shed - I find what looks like a shrimp carcass and it's really just a shell. I don't add anything special to my tank.

I've heard about it but like andreahp I have kept shrimp (red cherry and bamboo) without adding iodine or anything else and they molt, grow, and breed without trouble. I think it's normally not a concern unless you're in an unusual situation of some sort.

Please don't compare your shrimp to your friend's ; ) - as long as they are doing it there's no point in comparing frequency - mine do it pretty seldom also.

Shrimps need al sorts of minerals. However they need them in such tiny amounts that dosing the water with the raw ingredients is almost impossible. Good food, clean water, plenty of plant life are the main ingredients for a healthy and happy shrimp

Next, check the temperature. Even 1.5 degrees C of difference can already make a substantial difference.

There's some good mineral mixes for shrimps on the market. Look at a few and start googling what you select or make sure it's shrimp safe. PErsonally I wouldn't bother unless I got failed moultings.

This is brought up in the marine hobby quite a bit and even there its thought that iodine is unneeded for dosing by any vert. Water changes and quality feeding provide the needed trace elements.
