Critter ID! Almost overnight!

[Bender]

Hello guys! I have to critters I need IDing. They popped up almost overnight and they are all over the glass during the day. There's two types of critters:

One is a flat worm or something very similar:

And the other:

Sorry for the bad photos, my phone camera gets lots of lines from the lights.

#reefsquad can help. 1st is definitely a flat worm. I think the second is a pod, but can't really tell.

Isopod Munnid and Flatworms.

The good news is the flatworms are white not orange. The orange ones like to eat coral. The white ones are mostly food for fish...at least in my tank.

Awesome news so I dont have to work about either the isopods or the flatworms with my corals ?

As long as you have fish that like to eat them and you don't overfeed your tank and explode the population, they are just a nice addition to the daily menu for fish that like to forage throughout the day. If you have wrasses, you eventually won't have any left. They'll find them all. LOL Because the isopods were found on the glass, I also think they are Munnid isopods, and their population will also level out based on what feeders (including coral that can catch them) you have in the tank. No worries. If they are Munnid isopods and you find them on the corals, they are just eating what they find on the corals, not the corals themselves.

FYI: The isopods you want to worry about IMO are the blood suckers that like to attach to fish. They are fairly rare, but do show up on fish occasionally.

I agree with the others that the first is flatworms and the second is a munnid isopod

Thanks guys for your help. This tank just went fallow in attempt to quarantine everything for an upgrade which would explain the population explosion. Everything will be transfer shortly thanks for the info.
