If you replace the crappy eclipse bulbs with coral-suitable bulbs, then you can keep some shrooms and stuff. I would maybe use one 10K and one 50/50. If I had a 29, I would gradually add the following fish:
percula clown
coral beauty
flame hawk
bangai cardinal
-maybe- a sifter goby or scooter blenny
Just what I would do with a 29, not gospel of course.
