I sure wouldn't put labs in a 30 gallon unless they are babies and you have plans to move them when they get bigger . . .
A better bet in a 30 gallon would be SA dwarf cichlids. A pair of blue rams or a trio of apistos with a school of tetras would be lovely, colorful and suitable for that size tank.
