Adult Goby with Juvies?

Has anyone ever introduced a single adult goby to a handful of juvies? I'm considering getting a single tang. irsacae as the rock-dweller for my 29 gallon multifasciatus tank, with the idea that when I get a bigger tank, I can get handful of juvies and let him (her?) pick his favorite as they grow ;). Is this likely to work out or would I be condemning him to a live of bachelorhood (or spinsterhood, depending... I suppose I could always get her a school of dwarf petricola cats if she ends up alone)?

On a separate note, is the 29 going to be enough room for a single goby? I'm planning to have about 2/3 of the footprint taken up by a shellbed, with a rockpile on one end and maybe a solo rock in the opposite corner for a perch. I could reduce the shellbed to more like 1/2 with 2 smaller rockpiles (one on each end) if that would work better -- for a single fish though i'm thinking one big rockpile might be best though.

Anyhow, those who have kept gobies, please lemme know what you think! I'm not stuck on irsacae, but i think they're the smallest so I was thinking they'd be most appropriate for this tank.

There won't be a huge amount of water movement in the tank, but it will be well aerated due to the wet/dry filter in the 10 gallon sump.

My thoughts are that it won't work as well as you would like. First off, you are assuming that your first singleton goby will be a good breeder, of decent stock and genetics, and will accept a partner from among the juveniles later. Either way, it will out-compete younger/smaller gobies that may be better choices from which a pair should form. You essentially take away the choice from the other gobies. My experience has been that forced pairs do not behave as well as those formed from a group of equals.

My male gobies have outlived their female partners. Right now I've got two old widowers whom I don't trust with younger gobies. I reintroduced a female who had previously bred with the male in my avatar after his partner died, the three were a trio for about six months. But the widowed male bred with the 2nd female and then killed her. I hadn't anticipated losing all my breeding females, and so have been conservative with my growing juveniles, because they just wouldn't stand a chance against the older, larger, smarter males if they decided to be nasty.

Yeah, I was afraid that might be the case. I'm thinking I'll just go with another rockdweller until I get a bigger tank. Some day though... i wil have gooobieees!!!
