    Hi – can I just check you really mean 30 gallons? That only works out to about 115 litres. What are the dimensions of it? I’m not sure what the winters are like where you are but a pond that size could easily freeze in the UK. I’m afraid it would be way too small for carassius auratus, they can easily to get to over 10 inches long and pretty chunky besides.

    Danios are very active and prefer to live in groups, check the profile in the Knowledge Base for more info click me. I’m not sure their temperature range would cope if you had a cold winter, I wouldn’t want to see them in ponds in the UK as our temps get too low for them in winter.

    I would most likely bring them in during the winter because yes it freezes to almost solid. And by cold water I mean 60-90 degrees F so really just a big range thanks

    What are your average Summer temps? (you should be able to find these on a meteorological site). 30 gallons is very small, but I’ve found that once into warmer weather, water remains surprisingly stable (especially if it gets a decent amount of Sun).
    In the UK I usually leave it until the first proper warm spell in May, but then I’ve never had a problem leaving fish out for 5 months or more, you just have to choose the species.
    Aphyocharax rathbuni do well, they’re gorgeous and really shine in the sunlight, some cichlids do really well. It’s important to make sure that it’s a site where there is no chance of flooding, and not close enough to any natural watercourse that a predator might visit and take a captured fish back (due to diseases that may not be present in said habitat).
