Is my mollie pregnant or unwell?

my mollie fish have been acting really strange the black one has become outstandingly aggressive towards the white one and some other fish in the tank to the point the white dalmation mollie is jumping out the top of the hose when she settles she is against the filter with her head pointing up heavy breathing or she hovers over the bottom gravel on the reservoir doing the same
sounds sick not preg
draw from a book on fish illness, you probalbly need to get a oxgyen pump near probably struggling to breath

she might be pregent if the other fish are avoiding her

make sure the hose down is mature and do a nitriate test

but get some exepert advis
Answers:    She does not sound to good whether you have a hospital tank take her out and treat next to esha 2000, this is a great all rounder treatment if you do not have a hospital you will hold to treat whole tank remembering to remove carbon filter.
Hope this helps
