I was told by my lfs that a pair of Sleeper Golden Head golbies would do the job of stiring up the sand. Is this a good choise? The other tank mates in a 125 fo will be a 2in. Humu Huma trigger,4in striped puffer, 5 in Naso tang 3in Flame Hawk, and 18in Zebra Eel. I know a strange group but they all get along well together, I got the trigger small so hopefully there won't be trouble later on. Thanks for the info in advance.
