New frogspawn has something moving on it. The dark purple patch.

 

[cowboy]

looks to be a type of flatworm

Flatworm.

 

[loweryphil]

And this?
Yeah i thought flat worm but no idea if harmless or not. Coral doesnt seem to be damaged.

Not sure what we are looking for in the last image, perhaps circle it.

That particular type of FW can be problematic, I believe they are also photosynthetic so reduction in photo-period or black out can be beneficial. Keep on eye on population of FW, if it's red planaria then you want to intervene sooner rather than later.

 

[loweryphil]

Doesnt seem red. More like a dark purple colour

Is it moving or stationary?

 

[loweryphil]

Moving like a blob but snail like

Is there any way you can put it in a clear container for a better picture?

 

[loweryphil]

The purple thing?

 

[KJ]

The purple thing?

Yes.

I got flatworms that look same as top picture from a rock I got from another hobbyist. They don't seem to be eating any of my coral they only seem to irritate them as they go across them. I suck them out whenever I see them. I haven't seen one in a while but when I do I will suck them out. Flatworm exit would kill them but because rock they came in on is so porous I'm afraid I wouldn't be able to siphon them all out. Dead flatworms can be toxic so if you use flatworm exit definitely follow instructions.

 

[loweryphil]

These are the best i can get...

 

[LBehr]

Those are for sure flatworms. They don't seem to be the coral eating kind but if you don't reign them in they will end up taking over fast. Flatworm exit will kill them but make sure to siphon out as many as you can before and after using.

 

[LBehr]

I only had a few so I just sucked them out with Turkey baster whenever I would see them.

Some flatworm types are not parasitic to the corals but because they are photo-synthetic as the numbers increase the fw begin to cover the corals to absorb as much lighting as possible, reducing intensity to the corals that are plagued by the fw.
