I have one male Russian now and was wondering about getting more. I have pretty much read that it is not a good idea to get another male. So on that note should i get two more females at one time to keep the hounding of the male down or just introduce one at a time. (i know quarantine is a must at first). Also i do not believe the male I have is that old as he is just 4" long and i know its hard to tell the age from that but i was just wondering if that makes a difference. thanks
