I've had a twenty gallon tank with two dalmation mollies and three cory catfish for a few months and I really want some color in there, but I'm not sure what to put in with them. Guppies? Tetras? Anyone have any ideas?
 
guppies will be fine but just keep to the female/male ratios as males can get boisterous...same goes for your mollies 
 
tetras you got loads to choose from but id probably avoid serpae tetra as they fin nip and neon tetras as they aren't very "hardy" 
my favorites are Rosey tetra 
 
you got barbs...avoid tiger barbs as again they fin nip but cherry bards and golden barbs should be fine
 
another one of my personal favorites Pearl gourami's they tend to be the least aggressive of the gourami's 
 
ermm you got sword tails and platy's which are again the same as gupppies and mollies(live bearers)
 
...i should add by female/male ratios you probably know but if you have male and females always have more females...3 females to every male, which means you will have lots of fry
 
Careful with guppies in your tank; they are known to be able to cross-breed with mollies.  The resulting fry can be very weak, have birth defects, etc.
 
Platies may be a good idea, but platies cross breed with swordtails.  It's also worth noting that in my personal experience, swordtails just don't do well in 20 gallon tanks.  My swordtail, as soon as I took him out of a quarantine tank, started growing and growing.  He got pretty big and became quite the bully.  He started shredding up guppy fins during feeding, and started chasing my rummy noses, ripping their poor fins as well.  I had to rehome him, since he got very competitive for food and just became really angsty.  He was constantly pacing around, clearly showing signs of being cramped in too small a tank.
 
My favorite tetras are rummy nose tetras.  You can keep a small shoal in there if you'd like.  Neons are nice, but they are prone to diseases.  You could get cardinal tetras too, but they are wild caught and take longer to break into a tank.  After they get comfortable in a tank, they are much hardier than neons.
 
I'm suggesting small tetras simply because I like small tetras and I've never kept larger tetras.  Bigger tetras, of course, are always an option, but I don't have experience with them.  Plus, if you get a mini-shoal of small tetras, you might have space to get something else for your tank.
 
Keep us updated!
 
bleeding heart tetras. i have had them and some people say they're nippy but mine weren't at all. i also have kribs with some platys and they're not hurting them, just whenever they get too close to their cave they just chase them away.
 
First off, I'd get a couple more corycats. Then, if you're going for tetras go for cardinals or rummy noses. Be careful though, sometimes either cardinals or rummy noses can be very delicate depending on the supplier.
 
get some fish of the paracheridon species: AKA green neons and cardinals but NEVER neons. 
 
or you can get some nice firehead tetra. they are also called false rummy noses.... know the difference...
 
btw what coriecats are they? emerald, peppered, laser green?
 
More cories. Then some tetras. Then smaller gourami or betta.
 
Bettas are compatible with mollies and tetras? I do really want a betta..
 
Derp, they're peppered I believe.
 
If I put in a betta, what options would I have?
 
I think mollies would nip fins of bettas, if you got a female or a shortfinned male it could work.
 
It could... Ive tried it before but t was a complete disaster! Get some tetras instead!
