little parasites

hi there i was looking in my tank today and saw something that look like little white fast moveing parasites all over the tank glass i have a mng float glass cleaner so i swipe it back and forth to trying to kill them are they bad????? for the tank it's hard my snail has egg all over the glass and some baby's are moveing all aroung so it hard to kill the parasites


i have no fish yet but i have zebea hermits will they harm them i have a 50G bow tank with 100 pounds of live rock did they come from the rock i try cleaning the rock before i put the rock in my tank

 

IMO, they are some sort of plankton or pod and am willing to bet that they are beneficial to your tank food wise if nothing else!
Don't worry about them...I have them as well and they have't affected my tank negatively as far as I know!

 

sound good thank's for your help i was thinging my tank was going to hell lol

 

Fish parasites need fish to live.
