Hey all, I have a nano reef aquarium that I recently downgraded to from my 4ft (303 litre) tank due to school exams and a bunch of events coming up which means I have less time for such a big tank. Anyway, I am a fan of cleanup crew as anyone should be but I also like the personalities of some critters hahaha. I have a few hermit crabs (I think there are 4 left cause the rest were killed for their shells and I have now added empty shells), about 3-4 zombie snails, a few turbo snails, 2 strombus snails, a peppermint shrimp, and a tuxedo urchin. How is this cleanup crew? Should anything be added or removed? I had to give away my big trochus snails because they kept knocking things over and were just too big for the tank, but now my glass gets covered in brown algae a few days after scraping it all off because I don’t have those snails to eat it. As much as I like maintenance and cleaning the tank, I also don’t have heaps of time to scrape algae daily, so are there any cleanup crew members who can assist with that? Thank you!
