Okay. So I ask for two male convicts and the guy at the pet store was confident that is what I got. The two fish could not have disliked each other more, until now. I think they are making a nest. I have heard that these fish will kill a tankful of fish when breeding. I know that I need to get rid of them and am looking for a new home. How long do I have until they start laying eggs once they start this nesting behavior? It is really interesting to watch them but I don't want them to kill my other fish! If I were to get a "breed tank" how big does it need to be for them? Can't sink in a lot of money. What should I do? :shock: Dee :shock:
