ID NEEDED ASAP

ok i found these in a friends tank and they are in the thousands, possibly millions. They look like a form of nudi but maybe a pod? all i know is when something multiplies this fast that it's usually a pest. sorry bout the pics being bad but hopefully someone can tell me what it is.

Flatworms?

Looks like flatworms to me, doesnt look like pods to me.

I third the flatworms theory. I've had them in my tank before and they come and go. Some are really bad, others probably are more benign. Hit up wetwebmedia.com and see if you can get a better picture there.

Definately flatworms, some wrasses eat them or manderin gobys do if you get lucky.

As I understand them, the lighter more transluscent they are the less harmful the tend to be.... if the numbers are really as high as you think, treating the tank may be the only option short of a small school of six line wrasses or some other natural predators... we had a small population of the almost transparent variety gifted to us with some coral some time ago... a pair of six liners made short work of them within a week the were impossible to find.

What resides in the infested tank?

[greg97527]

i thought flatworms to. it is a frag tank that has misc xenia and rics etc we put a six line in but i think we will add more.

they multiply quickly, if you do use chemicals to kill them like flatworm exit, make sure to have change water standing by, when they die they emit a very very very toxin that will pollute the tank.

after some research it look slike the blue velvet nudi eats them almost exclusively and the six line as cr suggested as well as the spotted mandarin so we will be getting some of those before we try and chemical treatments.

Siphoning them out would be your best choice. Adding your blue velvet nudibranch will be the next good choice. A Leopard Wrasse would be good too.
