I got a 40breeder....I got it insanely cheap, around $65 for it brand new...If it doesnt prove to go well ill go with a tub or vision and put my JCP or Black milk in this 40 breeder, so it will always be useful for something lol...but it works out well because I'm going away for a few days, so my bp can get really used to his new enclosure and my black milk will be going in the 20L so they can all get used to it..
