Ok so I am now officially a saltwater tank owner(pics to come). Problem is the guy I bought the tank from neglected to tell me I was getting a small fish(I thought it was just live rock and water). Anyway, i got the tank home just a little bit ago and have to work early tomorrow. I would like to clean the crushed coral out and wipe the tank down and shine it up a little before I set it back up. I currently have the little guy in a 18 gallon plastic tote filled with saltwater and live rock(65 pounds) from his tank. I put the included pump on it for some circulation. Will he be ok like this for a day or so while I get everything up and running again?
