firstly, pikachu is not the species so its wouldn't be an "acropora pikachu"...... its just called the pikachu acro-nothing to do with what kind of coral it is.
secondly, no that photo is not it.
It is not a pikachu. However several sellers now have colonies that appear to look similar as the original pikachu from TCK. Any seller can slap an adjective name on a color form of a species or subspecies.
Not sure what species of acropora pikachu is. On above picture the growth structure and coralite structure differs from pikachu. Pikachu also is solid yellow. It does not have blueish colored growth tips.
I have a pikachu and it is yellow with brick red polyps. Not as bright yellow with stop sign red polyps. Like most online pictures many are photoshopped or shot with filters.
