I got a little extra

[KEVINM]

Hello all.. I order this off of a live sale and its a Wipeout chalice. And I noticed something odd growing on it. They grow along a viny path around the plug. Hoping someone knows if its good or bad.

Do they move or contract? Looks like some type of Clove polyp.

They will contract when taken out of water. I thought that to..just unsure of what they are

I agree with the other posters. They can and will become a major pest if left unchecked. I'd seriously consider taking that out of water, carefully scraping them off as best you can and then use a syringe or pipette to cover them in hydrogen peroxide. Use caution to keep the H202 off the chalice. let it sit on the area for several minutes then rinse in a bowl of tank water. You can then safely return the chalice to your tank, but I'd keep an eye on it to make sure they don't come back.
