And the second thing for us to know is, what type of water will you be using to do your water changes. If you don't know and you live in the USA, your water department is required to publish a water quality report yearly. In this report you can find out if your water is soft low PH or hard high PH. With this info we can then suggest fish that will live comfortably in your water.

Also Welcome to the fishy family!

This is important info for any newcomer! Just to add a little, call your water supply company and ask if they treat with chlorine or chloramines, there’s a difference in how you treat them

Welcome to the community! I always liked the colors on Geophagus and Severums, they created a peaceful and colorful tank when I had them together, maybe some smaller loaches since they grow slow but they can be a bit nippy I’ve found and need good hiding places, possibly a type of eel but look for smaller species, then you have smaller polypterus species but that’s getting into the predatory side. Good luck with your choices and happy fish keeping!
