I got a 5" male RES for Mother's Day, and had some questions on alternative housing. He's currently in a 10 gallon that I'm cleaning daily, because I have no $ for a 75-90 gallon aquarium, and the landlord is real touchy about "permanent" things added to the property, so no fence, let alone no pond... I was wondering what I could possibly house him in that would simulate a pond environment, but could be brought it for winter, or taken with me when I move? I was considering one of the rubberized stock tanks, lightweight so I can move it when it's empty (I have back and hip problems) but big enough that Chompers (my fiance named him) would be comfortable. And could I get away with a totebin until I find a decent stocktank? Also, with a stocking question, eventually I would like for him to have some companions; would 1 female be ok, or would a pair of ladies be safer/better? I know some animals need 2 females per male to prevent over harassment. Thank you in advance for any advice, Chompers and I appreciate it!
