Tiny Pond Stocking?

[Heiditron3000]

HI everybody! So, I recently made a little garden pond out of an old sink I found in my back yard (cleaned it thoroughly, plugged it up, sealed with fish friendly silicone, added a pump and filter, all that). It’s a small thing, 17 gallons. A foot deep, 1.5’ long and 1.5’ wide. It has a dwarf water lily and a ton of water spangles in it and then 5 rosy red minnows.

Can I add more/other fish? Would regular sized water lettuce like it? I live in Los Angeles so there’s no threat of freezing. The pond isn’t heated and the coldest it could possibly get out here at night is 40 F in the dead of winter.

I also seem to be predator-free because nothing has bothered the fish in the two weeks I’ve had them.

White clouds would do well

If that pond is outside, you are not predator free.

I would not add any more fish. Stocking in ponds is different than stocking in aquariums.

I'd add a snail or two since you have plants. They do a great job of "pruning" dead and dying growth as well as adding another dimension to your scape.
