Brown things on glass

What are these? Do I need to get rid of them? And if so how? I have like 7 that I can count on my glass.

Convolutriloba sp AKA Red menace flatworm. Keep an eye on them. Vacuum them out during water changes as you see them.

+1 with @Crabs Mcjones although he is pretty calm about them. Worms freak me out. Keep a close eye and if you start noticing to many of them i will link you a good thing to get them out.

Thats a flatworm, but is it the Red flatworm?

I had hundreds of these when I first started my tank. I introduced an Allen's Damsel and within 2 days there was nothing but a very plump fish in the tank. A wrasse would probably do the same trick. The flatworms didnt seem to bother any of the soft corals I had in the tank, though.

Wrasse or damsel, got it. They freak me out too, I keep wondering what corals they're eating.

Get some Flatworm exit and treat the tank while you have a low population or you will regret it.

None as theyre photosynthetic . The problem is they self divide until they reach plague proportions in turn covering a coral.and stopping it from receiving light .

Something's eating my montipora, it's got chunks missing where there's just skeleton. Isn't them? What could it be? I have suctioned out a number of the flatworms, will look into getting flatworm exit.

They aren't eating your coral. Worse they could do is cover your coral, thereby keeping light from getting to it.

Manually remove as many as possible before using FW Exit. The toxins the FW release upon death will wreck havoc. Some people report having to use 2-4x the recommended dose of FW Exit to eradicate the population.

I would try some natural predators that are compatible with your tank plan first (if any) before resorting to a chemical method of removal. My 2 cents only.

Could be alot of things but id start by looking for montipora eating nudibranchs under the coral and out at night.

I would really use flatworm exit as a very last resort. Get a sixline or another wrasse and it’ll take care of them for you. For sure they’re not eating your corals. However as stated above they can choke them out by covering them if you allow them to get to plague proportions.
