I have a 30 gal with an engineer goby in it now. I really want to pick up a midas blenny and a bi-color bleny. Can I put both in my QT tank at the same time? I want to leave 1 in the qt tank and put the other in my reef tank eventually, which one would be best in a 10gal? and which one should I put in the 30 with the engineer goby? The 30 gal has 2 ocelarius clowns and a blue tail damsel as well.
