Healthy krib

[lnmmenthol]

Hello I have this kribensis that has a much larger belly than the other 2. It doesn't seem to be a problem but figured I'd check here for some input. It is a female I believe but they are only 3/4"-1" long so I think they are too young for that. Could be over feeding too I guess but it's the only one with it so maybe not. I don't really think it's sick as it seems perfectly fine , just looking for some more experienced eyes. Any suggestions appreciated
Thanks
