I have a 20 gallon tank(thats been set up for 11 days),4 zebra danios & 5 plants.4 out of 5 have weird brown spots.The only plant that does not have brown spots is a large amazon swordplant.What is this brown spot and what can i do?
 
Might possibly be diatoms, a fairly common occurrence in new tanks. Usually the problem takes care of itself after a few weeks or you can get some oto's. You'll need them anyways and they love diatoms.
