What should I do with my 27 gallon freshwater tank?

[Beginner Fish Lover]

My aquarium is all cleaned up and looking good. I have 6 fish, of which I think are all community. I don't know what I should do. Half of my fish are algae eaters so i was wondering if there are any fish that would be a little bigger and better? Here is a list of my fish:
1 Plecostomus
1 Scissortail Rasbora
2 Green Cory Catfish
and 2 Assorted mickey mouse platies

If anyone knows what would be a good addition to my tank please let me know. If you need anymore info about this tank just ask.

Thanks,

Forget about adding new fish. Your 27 gallon tank is way too small for even one pleco, you need to find it a new home, it grows to 2' long!

Ok thanks. Any suggestions on what fish i should get?

Ok thanks. Do you have any advice on what fish i should get? And also would it be ok to keep the pleco until it gets bigger, because right now it is only 2 in.

How about a dwarf gourami? The one in my signature.

I just looked online and it said that dwarf gouramis do best with live plants. I don't have any plants would that still be a good choice?
