ID of animals on the glass

[christiantt]

I'm starting to see a lot of these on the glass the last couple of weeks.
The tank is 1,5 month old and started with Marco rock and matured with rocks from my old tank.
I've never seen them in the old tank and havn't bought anything new except for a BTA.
On the second photo I've zoomed in on them. They move with their "œlegs" last.
Is it planaria??

Flatworms, depending on which variety to have it could be bad to very bad!

Use a turkey baster to suck them out, and put them in a bucket of tap water, that will kill them in seconds.

Some wrasses will eat them. Be careful if you use chemicals to kill them as it can easily crash your tank.

I found 2 threads about some with the same shape.
It says that they not necessary are bad for the tank. So far I havn't seen them on the rocks and corals but will keep my eye on them.

If it's rust colored, it's a problem. If it's clear/slightly tan, no worries. The clear ones come and go, never get invasive. The rust colored ones can quickly get out of control and cover everything. I used a yellow coris wrasse to kill mine off. I've had them twice in two separate tanks.

The rust ones aren't bad as in killing off your tank and eating your first born. They're bad in that they tent to reach plague proportions and cover everything, smothering some corals in the process.

These are brown
I've removed those that was possible on the glass. Can't see anymore for now.
I'll keep my eyes on them the next couple of days.

I had the clear / tan ones recently and they started multiplying like crazy, then the just up and disappeared. I got a six line wrasse just to be safe.

Here's one under a microscope. Notice the dot on its back, you can see that with the eye if it's a large adult fw. This is the type that's not terribly bad.

Nice pic Cody!!!That's a pretty bad infestation. I had them back in the 80's just like that. Didn't have FWE at the time and it drove me out of the hobby for a few years. Next time they showed up, FWE took care of them for me.

Get rid of them now. Even if you don't see them now, where there was one, there are many others. The treatments out there now work best with smaller populations.

google, safe search off, turns up all kinds of terrible pictures!

Not my tank, but my infestation was terrible. Every surface (rock, coral, and sand) was rust colored...with little flappy-flappy worms moving around. The wrasse worked wonders. The second time it happened they died off before I got around to fixing it. The tank was a tertiary tank and I was busy with flight school...not much time to dedicate to it. One week it was all red, the next the flatworms were only in the sump, eventually they were gone. I don't recommend that course of action. I may have just let my water quality go to complete crap. Wait and see is NOT the answer for red flatworms.
