i went and turned on the lights today and i saw this thing making it ways across the glass, the picture is blurry but there wasnt much shape or distinction to it other then the forked tail or whatever it is... not sure if it was eating algae or just out for a stroll

That appears to be the distinctive profile of a common flat worm. The jury is out on if this particular type are a bad thing or just a distraction. The Rust, Orange and Red versions are definitely bad guys. None the less if you decide the distraction is just too much or feel like they are wrecking havoc they can be taken care of by a few natrual means. The best I have found is an Arrow Crab. Six Line Wrasses are aslo pretty good but more of a hit and miss proposition especially when other food is available. Worse comes to worse...use some flat worm exit but make sure that you remove any decortive shrimp, crabs etc...as it is liable to take them out too. This stuff while generally reef safe is not good for Anenomes, Cuttle Fish, Octopus and sensitive items such as Starfish. Have a 50% water change available and plenty of Carbon available for use after the treatment whioch will take about 6 hours to be complete. All of your copods and mysis shrimp will be wiped out by this treatment so you might want to use this as a last resort only.

I have used it on several occasions and will continue to use it as its the best sure fire way to remedy the problem especially in light of the number of frags I crank out pof my prop tanks and the numbers of corals I have comming into my systems. This is a good reason to QT all new additions in a seperate tank such as a 10 gallon tank. Prevention is far less painfull than the cure 98% of the time.

HTH's...

how are they bad guy? this thing is just clear, do they multiply liek your common FW snails? from what i see they arent too quick so i think i'll leave it be (unless they multiply quickly) until i switch over tanks it looked like it was eating bits of algae off the glass but i could be wrong, neat looking things though

they're BAD Richard... BAD BAD BAD..

There is only one way you can get rid of them... well two..

#1) go Ritsuko's way.. and take 6 hours to kill 'em

OR

#2) slowly go through the tank and take around 2.5 hours to pick em all out then EAT THEM

OR have a fondue with them..

invite friends.. family members... your boss... etc

and ROAST EM ALIVE








Okay.. my advice is 110% useless.. I appologise for my DISGUSTING behaviour!

what do they do to make them bad though

this would be what i have right here, looks exact

this is what came along with it

"Amphiscolops sp., a harmless acoel that "shows up" at times in reef tanks. Photo by Mike Giangrasso"

is there truth to that? i dont plan on keeping corals or anything anytime soon

The white ones dont seem to pose an issue but will multiply like there is no tomorrow more times than not.

The red ones are parasitic to corals, you need to get rid of these if you see them.


You can try an pick them out, but good luck cuase I promise you wont get them all. Natrual preditors will keep them in check but more thsan likely not totally eliminate them. Chemical Warfare though is pretty effective depending on tank inhabitants.
