what are they?????
 

k so i have these little things taking over my tank they look like tiny square brown mushrooms. there flat and are all over my rock the stick to the glass as well and have mouths like snails. i will try and get a good picture does any one know what they are and if i should be worried ??

Could be baby asteria starfish.......

Sounds like flat worms.

u are correct it is flatworms are there any ways of getting rid of these buggers or is it necessary. they seem to be helping my algae problem disappear

I've never had more than a few here and there but they all seem to get eaten. There are fish that eat them and some people have problems with them taking over their tanks but I haven't really looked into it myself. I'm sure I have seen posts on this forum about it, just do a search on flat worms and something will turn up.

Wow i was just about to reply with acro bugs! I agree, but i hope for your sake not
especially if you have an sps collection:cry:

Just google flatworm eating fish, as above there is a fish just cant remember ah old age sucks lol

well ive been looking around and i guess one of the best ways to get rid of them is too controll your nutrients in the water. i have been having problems with algea and nutrients in my water lately since my tank is very new only up for 2 months and still beeing stocked. i just got my protein skimmer up and working yesterday so hopefully with no fish in there and only corals and shrimp i can get this under controll. if all else fails i guess fltworm exit workes wonders

Or you can try using this..I placed an order with BRS and should be here soon. Have heard it works http://www.bulkreefsupply.com/store/...-test-kit.html Check out the reviews by some reefers who have used it and have great success.

Flatworm exit will exit your entire tank unless you follow the directions carefully :) Flatworms are toxic, and when they die, they release the toxins into the tank. And not all fish can eat them, again, toxicity.

They aren't a nutrient thing that will go away. Try manually removing as many as you can, then try the suggested fish (some wrasses I think) to control them.
