Different size fish community tank

[neutrino]

The Chalceus won't go well with neons, but are very nice. The Leporinus are nice for a nice tank, but not planted with most plants, and are too boisterous for most small fish (and capable of inhaling them). The Metynnis would be nice, and not impossible to keep in a planted tank, but it is not for most people as it will be a challenge in itself.

Agree to all of that, my point was these are alternative, less conventional options made possible by an 8 ft tank. Any of them would take some research before jumping in.

--Worth considering if you want to look into something different or something you hadn't thought of. But to each their own and whatever makes you happy is the thing.

Gymnogeophagus with other semi-aggressive to peaceful with other coldish water cichlids. Here is a pic of one of my Gymnogeophagus Terrapurpurra

Rummynose don't need a large fish to get them to school.

A large fish (circa 7-9 inches) would be some of the larger Hemiodus (orthonops, unimaculatus). Very active, hardy, a small group will grace an 8 foot tank, and will not bother the smallest of your fry, eat your plants, hide all the time, fight with others, and will last you about a decade. A wonder of a fish!

Amazon puffers aren't that big but might work. Certainly an interesting centerpiece.

Definitely have their own challenges though.
