I know a lot of people keep goldfish in aquariums, and I’ve seen some smaller species of koi kept in similar sized aquariums. Large platinum goldfish/small koi would b a cool solo fish imo

Definitely looking down the rabbit hole on a solo koi, not a common thing by the looks of it.

Koi can get to 4 feet. Maybe a freshwater puffer or Bichir would fit better. "Small" koi, such as the koi in Petsmart average 24" -- too big for your tank.

would a afer knife fit in a 125g?

I just read they can fit in 50 (which probably means 75). Should be enough for 1 or 2.
If the op wants to go brackish a moray would be a good option, you just have to train it to eat frozen.

Yeah, you’re right. I thought I read 30 cm.
