looking around the tank the past couple days i have noticed many tiny pocciliporas popping up all over one half of my tank. the count is over 20 and im sure when the light turn on more today i can find a lot more too. so far they range in size from smaller than a pencil eraser ( about 1/2 the size) to just larger than a dime. they seem to be growing really fast too. ill post pics when i get home from the dentist.
