No one can give me an idea of population numbers for a 20 gallon long tank ??

I started out with a 6 gallon tall/round tank with ghost shrimp only ... told my hubby about Dwarf Cajun crayfish and 'he' decided 'I' just had to have them too ... Ordered 4 - 6 arrived and I immediately realized the 6 gallon was not going to do for the shrimp and crayfish too ... Trip to PetSmart ...
