So recently I took some live plants out of my aquarium because I thought my axolotl was eating the stuff inside the containers. When I took the plants out i found that the material wasn't rocks at all, I could crush them with a fingernail. However, my axolotl appears to have some kind of lump at the end of his body right before the tail. Sometimes it seems to be smaller or larger, or sometimes I can't see it at all. I'm not sure what the gender of the axolotl is, so it may just be his male body parts (if it is a male) but I don't want to take any chances. He also has not had any decrease in appetite or production of waste at all, so I hope he is fine but I'm not sure could somebody please straighten me out?
