I was wondering what other fish I could put in my tank. I have a 20 gallon high with a Tetra Whisper 10i-30i. I'm also getting a heater for my tank. My substrate is gravel and I have a planted tank. I have 4 fish in it at the moment but i'm getting rid of 3 because they are too big or will get too big which include (2 molly sailfins and a really small common pleco). I'm not removing my Dwarf Gourami from the tank. I'm adding:
8 harlequin rasboras (4 at a time each week)
I want some bottom feeders because they are cute little critters. What else could be put in my tank considering what i'm adding and removing

Here's a picture of the tank right now

I think you could also add a peacock gudgeon or a bolivian ram to this stock, with what TD suggested.

What about 8 kuhli loaches? They're very cute!
TexasDomer don't kuhli loaches need sand to be able to live in tanks. I really want them but i've heard they can be put in gravel. Could I? I'm just wondering.
Here's what the gravel looks like

Guppies could always be an option. 3 females, 1 male.

Most eat their young and keep their population down to a nice size. Always remember to have more females than males so the girls don't get harassed too much.

Your tank is really pretty btw!!

Not a fan of guppies. Way too common.

They would prefer sand, yes, but if the gravel is soft, they'll do fine.

I'd rehome that pleco - plecos are too large and have too big of a bioload for a 20 gal high.

The gravel is quite soft but I'm wondering if it's too big
Here's what it looks like up close

The sand can't be too big. I agree, rehome the pleco....

A bolivian ram?

I am rehoming the pleco tomorrow. And your opinion is not get the kuhli loaches with my substrate?

Bottom feeders? I love my Venezuelan Pygmy Cories (Corydoras Habrosus). I currently have 7 in my 20G long.
Don't they prefer sand since the gravel hurts their barbels.

Tell your LFS to order some shrimp for you. That's what I have mine do.

Make it worth it to them. Order 10 or so.
So how many shrimp as my bottom feeders? These will be all the bottom feeders I could get right?

Generally, yes. Sand is preferred, but I've also seen other small cories kept on smooth gravel. I kept some aspirdoras on smooth gravel for awhile, but eventually moved them onto sand when I upgrade from a 10G to a 20G tank. My 2 cents, for what its worth.
