I am new to aquariums and this wonderful hobby, about six weeks in. I have two red platy's . In a 30 gallon tank with five seprae tretra's , three gold wags and six danios .
I notice over the last two days one of the platy's has been hiding on and off at the bottom of the tank inside or behind the plants. Staying very still.. When it's not hiding it is out with the other fish and seems perfectly fine. I also have noticed it looks a little bit fatter so I am not sure if she is pregnant. Honestly I don't know if it is a male or female.
I have attached a pic
Any suggestions on what is going on?
