I have 5 Black Widow Tetras, only one is female and she is constantly FAT and I mean FAT. I assume because of eggs but she has never layed any (I tried putting her in the breeder once with a male but nothing happened). She's been like this for months so I don't think it's a 'health problem'.
Can anyone enlighten me as to why she's constantly full of eggs but doesn't want to breed???
