Hypothesis test - What Type of hypothesis test is appropriate?

Im not sure what type of problem is this. I cant decide between a regular one-way ANOVA or a repeated measures ANOVA?

A preliminary study at Lady Elliot Island on the Great Barrier Reef was conducted to investigate how different species of encrusting sponge compete for and partition the space available on the underside of small boulders in the intertidal zone. Eight boulders were examined and the percent cover by each of three different species of sponge (determined by color) was estimated by using a grid. Is there a difference in the space colonized by the different species of sponges? Do a complete analysis using an appropriate test by hand (this includes a Post Hoc procedure if appropriate).
