I tried to have a "pod" tank for my scooter but it did not work. :-( Never generated enough food for the guy. BUT I did get mine on prepared foods, took about a month though and luckily I had pods already so he didn't starve in the meantime.
I have a scooter, mandarin, firefish, clowns, a yellow watchman goby and a citron goby and they all get along fine by the way.
