Are they still doing well?I say go for it. I got my pair directly from Biota in Dec right after my tank cycle. They're doing great and almost double in size now. They are the only fish in my 14 AIO nano reef but I'll be adding my yasha goby soon after he finish QT. I'll get a pistol shrimp later and maybe a firefish or orange storm clownfish too. Mine ate TDO B2 pellets the next morning after I got them and I trained them to eat out of a seashell now. They come very tiny so you might want to put them in a breeder box if you have other fish in your tank and if you have a large system. I seed my tank with EcoPods from AlgaeBarn for biodiversity but I mostly feed them pellets. it's better if you feed them a variety of diet including frozen and live pods but not necessary to have live food in my experience with the Biota one.
