Can anyone IDthis

[toothman]

I just saw these on the glass in my tank. Never saw them before today and I'm looking at my tank everyday. Are they good, bad or what?

 

[Harold Green]

If they're about an eighth to sixteenth of an inch they're probably a type of flatworm. Best to remove before they multiply too much to get out easily.

 

[toothman]

They are bigger than that. 1/4 - 3/8"

Flat worms its newer got in you aquarium get this out

 

[Harold Green]

Just a bigger version. Remove them.

There were 5 of them and they are out. I've dipped all my corals with Bayer Complete for over 15 minutes at the recommended amount. I wonder where they came from

 

[Tahoe61]

I am not sure they are flatworms, I'll look around but they look more like a Nudibranch than a Planaria. I would however remove them unfortunately. What corals or macro algae have you added of late?

 

[toothman]

I just added a boatload of corals but dipped them all. Sps, lips and a clam

 

[Tahoe61]

Did you use live rock?

 

[Tahoe61]

Need an image from the view of the top if the invert. Take one out, put it on a contrasting back round if you have chance, or have not already removed them all.

 

[toothman]

All coral were frags except for some lps ( lobo, trachy, scoly, plate). I dipped in Bayer and removed from the plugs the came on

 

[toothman]

Unfortunately I can't give you a view from the top. I played it safe and removed all of them, that I see that is.
