Ct Pregnant?

So I've got two Cardinal Tetra in the tank who are very heavy bellied, best shot I could get was this. Of the 9 there are two like this with the other 7 all looking 'slim' so to speak. Any ideas?

 

A bit overfed female ?

 

Could well be it. As the two biggest are the two who have the big bellies. May look at giving them 2 days off food and seeing if there's a difference? Bought a different food recently too, so perhaps I am overfeeding. Will underfeed and clockwatch next time I do feed.

Hopefully it is just that, at least it's in my control.

 

Doesn't really look sick !

 

Will just keep an eye on them. Their behaviours are absolutely normal. Plus, I didn't mean pregnant but carrying eggs. Either way, will just monitor. All look healthy, I do have a small bottle of API Melafix I put a small capful in each water change because I have a one eyed CT in there.

 

DoubleDutch Was indeed a case of overfeeding! Thanks
