I also like the Figure 8 Puffer, I had 6 of them 8 years ago..
they r just so cute.....but they r also aggressive.....coz I find my othe 4 Goldfish's beautiful tail been bite off so ugly.....and I did witness my puffers were chasing those poor goldfishes...
resulting I have to separating them from another tank...
and Brazilian Freshwater Puffer is nice too
here's a video of a puffer fish

I also have some Kuhli Loach, they r very unique and looks very like a "water snake"
I suggest for Glass Fish (Chanda ranga.)and Glass Catfish

The final one is Elephant Nose Fish...this fish has a very long nose
they r also very cute and very good to live with other tank members
