Hello everyone! I have a half barrel in my back yard that I want to turn into a mini fountain pond type thing. It is roughly 60 gallons and it is wood. will have a bunch of floating plants and I will try to make a hiding spot for what ever fish we put in there (what fish should I get?). I live in San Diego so it gets maybe mid 40s in the winter, what i'm worried about is the summer it gets in the 90s at most so will this be ok? Thank you!
