hey guys today i sat down and took a good long look at my tank (yes i was that bored) and i saw 2 things, 1 these small white ball type thigns on the rock, theres 4 now and ive seen them grow i had about 6 when they started, then some went away and others stayed/came back, and in the 3rd pic you can see these vines on the rock tooi just wanted to know what they were and if i should do anything about them ill post a pic down below, the last pic is just to show were in the tank they are. another thing i would like to ask, iknow this is the wrong section but in the pics you can see the colour of the shells on the floor of the tank have changed from bright white to this dull colour, if anyone knows what to do about it, that would be great help.
