So I've been searching the forums and just in general. My Aquarium is probably 8 months old now let it set empty for a while noticed some flatworms narrowed it down to probably white planaria....also noticed a bunch of very small Yellow worm like things on rock and glass with little tentacles/strings. Any suggestion on what they are. Moved a bit of my GSP from another tank into this one and it's super un happy all my levels are fine and light is sufficient and flow. Only thing I can think of is either the flat worms or these little yellow things aggravating it.....
