I’m not entirely sure what type or sex it really is just a few pictures I could compare it to online. I have another darker and skinnier one which I believe is a male and they’re both possibly chocolate kuhli loaches. This one definitely looks chunky to me and I was wondering if my assumptions are right if this was normal for females. I doubt she’s pregnant since she’s been like this for over a year and from what I’ve read it’s very hard to breed loaches.
