Does anyone know if these are bad? I only have one frag plug in my tank right now which is only a few zoa polps and GSP. They seem fine but, I worry if I stick anything in there now that the flatworms will go after it. they mostly just chill on the glass and my pink streak will pick at them every so often but, not all the time. If I can I'll try getting a good picture of them or see if I can find one. Only reason I'm not to worried because the ones that I've seen online that are bad usually have a more rounded body or a "w" shaped tail with a narrow mid body and a big head. these ones just look like a boggy board.
