I had the Koi for about a week and yesturday I saw the other guy and just had to take him, I am not sure what kind he is he seems to have veil tail. I have these 2 right now in my 36g with a school of rasboras and 4 albino corys ( The will be going into my new 125g after Christmas.) So meet Tom and Jerry. I did my best to sex them I think I might be right, if I am not please chime in! Can you tell my kids named them. This is Jerry my newer one..sex and type if you can. I think he is a male Jerry Tom I am leaning on Tom being female Thanks for your help and time!
