ok i have has many sw tanks over the past few years and have not seen or heard of flatworms till now?? i have read some things that say all flatworms are bad and some say that the white ones are ok? the ones that i see in my tank are withe, are they cause for concern or what? there are quite a few of them in the tank, it is a mostly coral tank! What should i do, if anything???
