Just bought a female sp Borneo Black (as advertised anyway), yet I'm concerned as this 2.5 in specimen is still very brown so I'm thinking my she is a he. . Do the females start out brown? Or does the black not fully come out in females until they fully mature. I've been burnt on one of these before so i'm just feeling around as there must be a few people who have gone through the process with this species. Not much info out there on these guys, or good advice anyway. Thanks in advance
