i have a Platinum Lyretail Molly, black molly, red wag platy, and 9 fry in a breeder box in a 29 gallon tank. The tank is kept at a temperature of 80-82 degrees and is filtered. A few days ago my Platinum Lyretail Molly started acting strangely, she was less active, and keeps hiding in plants and only comes out when feeding time, but then goes back. The other fish are fine they are very active and also i am not sure which fish gave birth to the fry because they are all female(i think it was the Platinum Lyretail Molly because all of the fry are white). could she be sick or something?
