Dwarf Puffer Sex Change

  1. BodaciousBetta Initiate Member

    So I have had 2 dwarf puffers in a 55 very heavily planted aquarium. They were both barely bigger than fry and one assumed the male sex. The one that ended up being female now seems to be morphing into a male. I have had these guys for about 6 or 8 weeks now. I have done hours and hours and hours of research. Is it possible for my puff to change into a male? Does the tank size/visibility/plants etc play a factor at all in this? She has had the appearance of a female this whole time, but recently started changing after more wood and plants were added

    These fish can't change sex. Most can't. As they start to mature, their sex will start to become more apparent. It could be that this puffer is only now starting to mature :) sexing them when so young can be very difficult
