so about last june probally about june 6-8 2010 a black female gave birth to my now lucy and sophie. i have just tried introducing a male i have a fifty five gallon long aquarium so space isnt an issue (especialy seeing as how breeders use 20gallons) i also have a 20 gallon for babies ive let them play for about 20 minutes today i think i saw a mating ritual but i cannot remmeber. my gerbils are identical so the pups should look just like mom and dad right also they should mate successfully with each other right ive already seen grooming with lucy and the male (xaivier) thats good right? i also got the male from a pet store i dont have any breeders in my small town
