20 gallon start up

[OwenBrewer]

I'm about to acquire 2 55 gallons and a 20 gallon thru a trade on craigslist and I'm actually going to mainly focus on the 20 gallon.

Here's what I was KNOW will be part of the set up.

20 lbs. base rock
5 lbs. lives rock
HOB filter rated for 60 gallons.
Heater, I forget exactly how many watts but it is big enough for this tank

Everything else is up in the air, this is where I need help.

Sand/crushed coral/aragonite ( I'm leaning more towards crushed coral)
I found a HOB bio skimmer for up to I think 29 gallons online for like $50, should I get it with as much filtration as I already have?
And also lighting, I Honostly just have no idea what to get (I would like to have soft corals)

Livestock

Pair of oscellaris (probly not even close to spelling that right ..) clown fish
Pair of fire fish
And then some hermits and snails, the usual lol.

HELP HELP HELP. Thanks

Ummm okay, you dont need a skimmer for a nano tank like this.

Get sand, not crushed coral. Crushed coral will lead to nitrate problems in the future.

For your stock i would suggest 3 fish, maybe 4. I think your list is OK right now but i wouldnt add anything else to it. And its spelled ocellaris*

I've read that you can only keep 1 fire fish unless you get a mated pair.
