so far im thinking
3-Dwarf shufeldtii crayfish
or
some kind of personable cichlid
but what would you do?

actually im thinking about getting a marble cray, or a blue marbled cray, or an electric blue cray. could i keep a convict with any of those? what would i need to raise the baby crays?
First let's establish, as well as we can, the exact species of crayfish you listed.
If you're keeping dwarf crayfish, like the self cloning Marble cray, the cichlid would devouer them. Depending on how hiding places, the crayfish might be able to sustain a population. However, they would be harassed and would never flourish. If you're keeping a non dwarf species, such as P. alleni, the crayfish may kill the fish, or the fish may kill it off when the cray molts. So, no, I would not recommend keeping that type of fish with any kind of crayfish.
The first thing you need to decide is, are you going to keep a dwarf or non dwarf crayfish species. Here are a few things you should consider, if you plan on breeding. A single 20L is not enough to breed non dwarf crayfish. To breed P. alleni, or P. clarkii, you need three tanks, at least. One for the adult female, one for the adult male, and a third nursery tank. When you want to mate the crays, you move the female to the male tank. If you put the male in the female's tank, she is just as likely to attack the male, as mate with him. Once the female is berried, she is moved to the nursery tank. Leave her there until all the eggs hatch, then move her back to her home tank. Now you have to deal with, ideally, 50-70 young. As they age they will slowly die off, as they compete for resources. If you're going to sell them, you should have buyers ready before the young are over an inch long.
Since you're talking about a single 20L, I recommend that you go with a dwarf crayfish species. Personally I don't care for the self cloning crayfish. They all look exactly the same , obviously.
Depending on how much you budget, you can get some vibrant Cambarellus patzcuarensis sp. var. orange (CPO). There are also color morphs of Cambarellus shufeldtii (blue, brown, white). Do not mix colors variations of the same species in on tank.
So to sum up,
You can keep a single non dwarf crayfish in a 20L, but only house it with fish you don't mind being dinner. Don't use living plants. Plan on the crayfish redecorating your tank. On the other hand, you can have a colony of dwarf crayfish in a 20L, with a mix of other species of dwarf crays, dwarf shrimp, and placid fish.
Good luck!
1. I assume you mean the self cloning Marble Cray, Marmorkrebs or Procamarus marmorkrebs (the scientific name is under debate).
2. I don't have a clue. Are you meaning that there's a blue var. of Marmokrebs? If so, I have yet to see them.
3. I am confident that you're referring to the P. alleni var blue.
OK, this question varies a bit depending on what kind of crayfish you're getting. But the basic answer remains the same, no.

i decided on the first dwarf cray i listed 
people will probably see them on the marketplace in a month or two.
