Looking for someone with experience of buying corals from masterfisch in France, have you noticed any signs of pests?

I bought CUC from them so I know their shipping is nice.

Thank you

Added CUC, cleaner shrimp is doing goody trochus snails cleans rock and sand 100% every night. Nassarius sleeps until I feed pellets then they come out like a bullet.

The only thing that’s not good is my two hermits, 1 was very active on day 1 the next day it’s gone, I can’t find it, and I can’t find its shell. I’ve seen a leg and a arm lay in the sand, has it died or morphed, what do you think?.

The other hermit is almost frozen, it has moved 5 inches over a week, I can see it cleaning it self, it doesn’t eat, and reacts slowly.

Doing a cycle with homemade ammonium chloride. Works well, dosed ammonia up to 1.5 took around 4 days to get to 0.

But my nitrites is high, around 4 which is to be expected but I think it’s been a long time now, a couple of weeks. Nitrates is 50,

I did a 50% waterchange yesterday, nitrates went from 90 ish to 50, nitrites stayed the same at 4.

Should I just wait it out and hope the nitrites will drop, or do another big waterchange?

Anyone recognize what’s on this fish? It’s a black clown and a white clown sold as a pair, but I’m concerned of their condition… and yes I have seen the aptasia in the tank also
