Wait, I'm very confused by the tank dimensions. Is this a 10 gallon tank in total or are you splitting a 20 gallon to make two 10 gallon spots?
And as for the pygmies, I wouldn't do that because they are very active fish and only having 10 or 5 gallons each side will be bad for them. Pygmies and Dainties both need a minimum of 20 gallons for a group if not longer since they really like to swim a lot. So with a split 10 gallon, I really don't think you should have more fish in there. You can try some shrimp but the girls might eat them so just be warned with that is all
aqadvisor is a great site but further research is almost always required since they just calculate bio-loads and all, not always compatibility or tank requirements. So you're doing well with asking the forum ^_^
