I wasn't sure which forum was appropriate for this, I figured maybe this would be best, since I do have live plants and it could be related? Well, in my tank I have hornwort (it shed all it's needles when I first got it from the bleach dip a few weeks ago but it's growing very fast now), an anubias and java moss. A few days ago I noticed some very tiny things attached to the anubias leaves and after looking some more, there's some on the hornwort and on the gravel. They have a tiny (seemingly) stem and from that, about 5-6 thread like things that float around in the current. The thread like parts seem to have gotten longer over the few days. Is it..some kind of fungus? or? I have the temp at 78, 0 ammonia, 0 nitrite, about 5-10 ppm nitrates. I use a small amount of aquarium salt and prime. I do about a 30% water change every wednesday as I have some brown algae and I want to keep it under control. I hope you can see it in the pictures, it's so small and fine, it was hard to get it to show on pictures at all.
