Dumb Pond Question - Stocking
Heya. So we're in the process of beautifying our apartment and, since we have a nice little patio space and me and my GF both enjoy fish, we're considering a pond.
Considering that we're at an apartment (so something that could be moved and doesn't disrupt the property is necessary) and have a relatively small space available, we're considering a container pond. Since our toolset is limited, we're likely looking at something prefab (like an Aquascape kit or a Smartpond kit).
The problem is, when it comes to what can actually be done with a pond that size, I'm getting incredibly mixed information. So I was hoping you all could help me out.
What sort of fish can be stocked in a small-ish pond (let's say 50-ish gallons, something like 30x30x14))? My understanding is this is 100%, definitely too small for koi. But I keep getting mixed reports on goldfish/fancies. I've heard everything from requiring a 100 gallon minimum for a single fish to being a couple being okay in 50 gallons. This isn't particularly helped by the variety of stockings for similar ponds I've seen.
So does anyone have any thoughts or resources they can provide to help me?
EDIT: Right, probably worth mentioning. I live in South Bay in CA, which means that freezing water is very unlikely, but it can get fairly warm (still sub-100). I know this makes a difference with water depth.
