Pregant catfish??

[parrot_man]

exactly one week ago i purchased a breeding pair of pearl bristlenose plecs, when i go thome i put them in my 30 gallon aquarium with my other common plec. i removed the breeding pair the following day to a tank of their own! today i noticed that my common plec in my 30 gallon tank was fat and looked as though she could be pregnant! is she pregnant? could bristlenose's and comon plecs mate? or could you explain what is wrong with her?

As egg layers, i can assure you that she is not pregnant, she maybe egg bound or bloated as a result of poor diet or over eating. Catfish dont get pregnant so worry not, there is no chance of you decomeing a fishy father.
