well after seeing pitbulls. ive decided that im making an outdoor pond. im not sure what i want to have in it but i want something that will survive in texas year round (hot in the summer and only like one night below freezing in the winter) i have the feeling that koi and goldfish are my only option but if thats the case that would be fine with me. i want to build it like pitbull has his built but im thinking that bigger would be better. perhaps 5deep x 5high x 5 wide x 12long (those are in feet). i will have to make a filter. i figure i can get some info on that either on here or from my uncle who has several large ponds that he keeps koi in.
