Fish/fish not eating


I have had 7 male mollies for 4 months in a 40 ltr tank, I do a 20% water change fortnightly ( last one 5 days ago) one of them is not eating and is hiding,I can't see anything physically wrong with him, another one in particular keeps chasing him, what do you think the problem is? Could he just be having an off day? Thanks.

Hello Linda, Do you have any female mollies with the males? or do you just strictly have males? Male fish of any species can sometimes bully each other around. The odds are you have a male molly that is the least dominant in the tank and that is causing him to hide. The others may be harassing him that would cause an issue. I would say that you could add a few more hiding places with either live or fake plants. That should help your problem. As far as not eating, he will eat when he gets hungry unless there is a problem internally with him but I do not think so. Does he hang around the filter or in the corner of the tank at all?

I can answer most questions about fish care and maintenance. I am not an expert on saltwater aquariums but I am researching more about them on a daily basis. I have kept many different tropical freshwater fish as well as cichlids. Brackish water is my weakest category but if you have a question feel free to ask and I will do research on it myself.


I have kept fish for over 10 years. I am also an employee at a pet store and the head of the fish department. I am going to school at Emporia State University and studying biology with a concentration in ecology and biodiversity for undergraduate work. Right now my job is to care for and maintain the fish department at a local pet store. As far as water quality, I am well versed in different practices you can do to help improve conditions and what levels to look out for when testing the water.

I am majoring in Biology at Emporia State University and have researched fish reproductive behavior for the past decade.
