hey, im a newbie here to the forum, i am just wondering if it is normal for a platy to "run up the side of the fish tank", what i mean is, its as if they are eating something off the sides, but i had just cleaned it (to put in some gravel and such) so not sure if it is algae or not. i have one of them 1 gallon starter tanks with an air pump and a light on top. oh and i have 3 platies in the tank.
thanks
thanks
