I agree on the black ghost knife idea. They are super fun to watch and is perfect for your 20 gallon. But yeah, it will probably need a 40 or 60 gallon later later later.

They grow pretty quick... My sister has had hers for about a year and it's already 12" long.

I love watching freshwater flounder, and would work well in a 20G long.

One green spotter puffer. Amazing to watch them buzz around. They are amazing eaters too! Check out my vids. youtube- kjfanbass

4 pea puffers! They are super cute and fun to watch, plus they aren't really a typical fish you see in the smaller tanks
