Hi Tracy, how long have you had the cory for?

Have you noticed it going to the loo ie is it white stringy poo?

What do you feed them and how often?

In my experience this is a swim bladder problem, unfortunately my cory died recently after exhibiting this same symptoms.

Hi Tracy, how long have you had the cory for?

I've had the cory for around 6 weeks,haven't noticed any white stringy poo from her,

I feed all the corys tetra prima granules 2 x a day ,bloodworm(defrosted in a little tank water first) and fast sinking algae wafers weekly.

I was wondering if it was swim bladder,a few days ago i tried giving her a de shelled pea,but she just nibbled it,

I meant to say i did treat the tank the 2 doses with interpet 9 for anti bacterial infections has the platies had stringy poo,but i have done the water changes and added carbon to remove leftover meds,that was a week ago.

well update on cory, Not sure about her,she appears much the same but doesn't appear to be floating around now,i was wondering whether she ate some of the pea and that helped her???

She remained in the net for a few days,i've put her back in the tank,she still looks darker than the other 2,she does move around but not overly active?

Any ideas?
