double check them... for most reef tanks, 5-10 trites is bad... 5-10 trates is ok. IMO, 5-10 trates is a bit on the high side for a 29g, only because they can fluctuate fairly quickly in that size tank.
If you're one who tends to be a bit on the cautious side, don't get the fish. If you push your tank right to the edge, and can tolerate a few potential losses (which I don't recommend), then go for it. IMO, you're right on the borderline... you could be fine, it could put you over the edge.
