Sick Clown

[MadReefer]

Gave my mated pair of Clarkii clowns away and they reside in a 20g tank by themselves. The person added a few snails and crabs which died and the female clown is not doing well. It had white stringy poop and leans to the side a few days now but will swim at times. I see no physical signs of injury. The only thing off was nitrite was high but using Prime that came down. All other tests show in range so wondering what can be the cause. He wants to give it back but if its sick don't want back in my tank.
Tank is up about a month cycled with live rock from my tank and live bacteria. Any help appreciated.

White stringy poop usually means internal parasites. Prazipro can be used in the tank to treat the fish.

I though of that but otehr clown is fine. i am wondering if teh snails / crabs he picked up brought in something.

I've had one fish sick from Parasites but not the others. Prazipro is worth trying and maybe use some Garlic on their food

I add human grade probiotics 1x a week with frozen food
I break open the capsule and sprinkle some in with the food. Fish seem to enjoy it

If the fish is eating, Metro + Focus + Garlic will clear it out within a week.
