Stupid Mollies

[Sotsog]

I have just introduced 3 quarrantined mollies into my aquarium, and the females are now prgnant, and have developed yellow spots on their belly(what is it?) also the mle is attacking one of the females, but not the other


as well as that, i found my 2 year old albino cory belly up on the botom, on further inspection, it had small pinhead sized red dots on its back, what could that be? no other fish show symptoms.

Thanks

Luke
