Last night and today I have seen some planaria looking little organisms cruising around on my glass and some of my frag plugs. After doing a search I have determined that they are some sort of flatworm. Right now they are not of biblical proportion, but I don't want it to get to that point. I saw that you can kill them, but that can toxify the water. I also saw that you can add certain wrasses to do the trick. My issue is that my tank is only 8 gallons and I don't know if that's too small for a wrasse, even temporarily. They are too small to siphon, and after reading that they put of poison when they die, I don't want to squish them on the glass. I have started a nice little coral collection and I don't want to lose everything. Any and all advice is welcome.
