Male or female Sewellia lineolata?
Posted: Tue Apr 28, 2015 8:49 pm
Good evening--new to this fish and this forum. I've had this particular fish in a tropical aquarium setting for a month or two, having been led by LFS to believe this fish did not have specific flow/oxygen needs. I don't expect much from the kids at the LFS because I normally do my research. I feel bad for not doing it sooner in this case--I'm working on building a long narrow tank with a manifold per Martin's design. For now, the fish eats and moves around the 37g tank, supplemented with an air stone, enough for me to know it's healthy.
I'd like to introduce a few more S. lineolata to the hillstream environment once I finish building it. I have read through most of the great resources on this site, and saw the guide to sexing them, but I only have in-person experience with this fish, so I wanted to ask people who would know. Here she/he is:

Pec fins make me lean toward female...

Slope of nose makes me think twice.
Is that just paralysis by analysis?
Also, I'm considering making my hillstream tank a S. lineolata species tank--any drawbacks to that? Any benefits from including other species?
