Psychiatrist ?

if your tank is measuring nitrItes, then it's not properly cycled. do you have a nitrAte reading? this is what you should be looking for, as it is a sign that bacteria are getting rid of the toxic ammonia and nitrItes.

how long has the tank been set up? how did you cycle it?

the flashing and rubbing against the substrate really does sound like parasites... i'm glad you're going ahead with the treatment.

bear in mind that we are not trying to be rude... we are all just looking out for the best interests of your fish!

usually, no matter what the case, if someone posts an oddity about their fishies, everyone has to chime in as to what might be the problem... it's just that we all care very much about the welfare of the living creature you're charged with caring for to the best of your abilities!

on the other hand... if we can clear up any possible outside problems, maybe we can not feel so guilty about being amused by the psychosis of your fishy. many animals have their own personalities and little ticks... maybe that's just a part of who your fishy is... but we just want to make sure!
