I have started a new 75 gallon tank... It's planted ... I intend to put goldfish in it once cycled. I put plants in last week and am now seeing white mold on the plants.. Not on the leaves - just on the roots/rhizomes.... What's going on... They don't really seem to be melting. What's is this stuff!?!? I have pulled a few plants out and washed the yuck off ... It is killing the plants.. They are getting mushy! Got rid of all the yuck I could and re-planted them but almost all the Anubias nana and some of the cryp parva are now affected. Help! Please! Look in the center of the photo.. Just under the leaves... It's a white-ish fuzzy mold with tiny bright white dots ...... This is super upsetting as I have spent so much money on these plants!!!
