looks male to me, but either way needs to be beefed up a lot

Head shape says female. But its hard to tell.
Also if you enlarge the 1st pic, There seems to be a female breeding tube.

venting is really the only way to go with synspilum. and I don't think this one needs to be beefed up. it'll grow length wise and then as it stops growing in length is when it will really put on some girth.
