Looking to add fish need ideas

[fishinstaller26]

I have a 72 gallon tank
Currently housing 3 small angels
1 gold gourami
3 platys
4 zebra danios
3 Cory catfish
1 discus

Looking to add more fish
What are my options
And mainly looking for some ideas of things that might look cool it is my main tank and kinda a centerpiece

But the gourami may need to be moved he is chasing the platys a lot

How's your discus I've been looking at getting some, I'd do some peaceful cichlids like a festvium or severum or geophagus or maybe a black ghost knife I love mine they can be a little tricky to get to eat at first but after that it's all love I have a uaru too he's very unique

He's good had him for a couple days doesn't bother anyone keeps to himself
Just a lap or 2 and goes back under some driftwood

First on the more fish list:
At least another couple Danio (if you've started with Zebra stick with those). They should be in a MINIMUM group of six.
Same with the cory, and again, the same type.

Also: are your platys all male or all female or a mix? Cause if you've got both you may soon find your tank full of fish, although other inhabitants will gobble up any fry they find.

I'm not sure on the sex the platys

Have a look at the bottom (anal) fin.

On a male, it will be a single horizontal line or "rod" shape.
On a female, it will be fanned out the same as the top (dorsal) fin.
