Strange tiny white creatures on glass 55 Gallon Tank

  1. pappy Initiate Member

    I have an established 55gal tank and in the last two week or so I have been noticing what I first thought were mineral deposits. They look like tiny white lines maybe a millimeter long. Upon closer examination I realized that they are moving on the glass and appear to be alive. The fish seem to be fine- no visible signs of sickness, they are eating well and remain active. Anyone have an answer? Should I be concerned and what is the solution?

    welcome to fishlore pappy!
    sounds like nematodes or planaria...which are usually caused from overfeeding(my issue) or new tanks ....they dont hurt anything and usually most fish will eat them...extra gravel vacs will cure it and less feedings
