Welcome to R2R! Agree a clownfish laying on the sand, with stringy poo and not eating, sounds like it may have a problem.

Hi and welcome to Reef2Reef!

 

[reefertanker]

Could I be from the hardness of the water? I know that they don’t like spikes in parameters and when I dosed it I pour way to much. Would that affect her?

Welcome to R2R!!!

stringy poop is usually a sign of internal parasites

 

[reefertanker]

She was a captive breed clown I thought that they only got parasites if you got it from the ocean? Otherwise what should I buy?

Welcome to R2R and the salty world. Purple seems like coraline and good for tank. Hope your clown improves. Lots of knowledgeable and helpful people here who will support and advise you when needed.

Might have caught it from another fish between breeder and your home.

This post from the Forum may help, but you'll sort of have to back into symptoms:

Medications to keep on hand

These are the bare essentials I recommend for quarantining: Anti-parasitic: Copper Power with a Hanna High Range Copper Colorimeter (HI702) for testing. Treats Ich & velvet. Anti-parasitic: Metronidazole (e.g. Seachem Metroplex); treats brook & uronema. Dewormer: Prazipro or API General Cure...

Welcome! I'm jealous of all the purple coralline in your tank, looks nice.

 

[reefertanker]

Will coralline over take my corals? Last week I was good now I’m down to 3 corals. 4 of them died or were dieing from coralline covering them. Is this natural??? Please help!!
