Hello, I am fairly new to the reef aquarium hobby, although i do have plenty of experience with freshwater. I was hoping for some recomendations on what cleanup crew members I should have for my aquarium. I am in the middle of cycling the tank which I cycled with a raw shrimp (very smelly and I don't recommend), and I have an aqueon 15 gallon column tank. I know this tank isn't really ideas considering the footprint of the tank, but I wanted to go ahead with it anyways because for some reason I am just attracted to the look of it. I have an aquaclear 50 HOB filter along with a 240gph powerhead and 12 pounds of dry rock and 5 lbs of live sand. I have been cycling for about 3 weeks now, but I think I am just going to keep cycling for another month just because in 2 weeks I am leaving for a 2 week vacation so its just convenient. I am planning on keeping 2 ocellaris clownfish in the tank and thats it for fish. But I don't really know much about what would consist of a good cleanup crew that doesn't overcrowd the tank too much. I know if you have too many snails in such a small tank, one could die as there isn't a sufficient amount of algae and sorts to go around so some could starve and add an ammonia spike if death occurs, and I want to avoid this. Also any tips are much appreciated as I need all of the information I can possible get, Thanks!
