Get yourself a snail, hermit crab...uh no wait, scratch the hermit crab...
...and the snail might not be safe either! You can try though
...and a brittle star. They all eat detrius and help keep nitrates down. Brittle stars in particular are omnivores and will eat the mess the octopus makes. Octos usually leave them alone too.
Go here and pick some things out, hopefully your local store has these in stock:

Here's a quote from their site:
The
Atlantic Astrea snail loves to graze on algae. A very active cleaner, it cleans both algae and diatoms. According to Julian Sprung's Reef Aquarium Manual , Volume One, Atlantic Turbo snails are the ideal snail to be placed in your aquarium as soon as ammonia and nitrite levels reach acceptable levels (less than 1 ppm). One of the best snails for controlling Diatom's (light brown/red algae), Green Algae Blooms and Dark Purple/Red Slime algae . Introduced as soon as possible to new aquarium, these snails effectively limit the development of all microalgae.
And about
Bumble Bee snails:
Totally Reef Safe, they are about 3/8" and look like Bumble Bee's. A great scavenger, cleaning up both your sand bed, rocks, glass, and they take care of diatoms, hair algae, and red slime too!!
And on
green brittle stars:
A good garbage cleaner for your tank. Brittle stars are one of the best detritus removers for the aquarium. (Detritus causes high nitrates). Keeping the detritus (garbage) down in your system, promotes cleaner water, lower nitrates, and healthier animals. Totally reef safe.They are also interesting to watch.
