You do not need an expensive LED
fixture for a low tech tank. If it's in the budget, then knock yourself out, but otherwise I'd stick to T5 HOs for cost effectiveness. A 2 or 4 bulb fixture could support everything on the list with the exception of the flower pot (Goniopora), which I would not recommend purchasing at all. Even a lot of experienced hobbyists can't keep them alive.
Is this stocklist overload?-
2- Clownfish, one orange, one B&W
1- Six Line Wrasse
1- Neon Blue Goby
1- Zebra Barred Dartfish
Too many fish here IMO
. I'd go for the clown pair and either the sixline OR the dartfish. No more fish, that's plenty.
5- Blue Leg Hermits
5- Red Leg Hermits
1- Dwarf Colored Feather Duster(not CUC just had to add it in)
1- Peppermint Shrimp
3- Nerite Snail
1- Tank Bred Peppermint Shrimp(don't get the difference, except the colors)
1- Margarita Snail
3- Bumble Bee Snail
3- Nassarius Snail
1- Banded Trochus Snail
3- Cerith Snail
You've got way too much going on here for a 29. The margarita snail can't right itself if it falls over, and iirc it prefers cooler water than the other stuff you want. Bumblebees don't do a whole lot IME and you won't see much of them. Hermits may kill your snails for their shells. They can be a pain.
Are these good coral choices?-
Zoas- lots of different colors
Yes, with the exception of the Goniopora as mentioned above. Zoas are the easiest to keep out of that list, so I'd start there. If you like mushrooms, they're a great beginner choice too. Lots of colors.
Filtration- you'll get mixed opinions. Read up on sumps and see if you want to go that route. If so, have a glass shop drill the back of your tank. Don't waste your money on HOB
overflows- speaking from experience, they can be an absolute nightmare.
