Sorry to here about your crash man, that's always a downer.
What I suggest for that small FW
tank your planning on doing.
I wouldn't put neons in it, that would be too small for them, 5 gallon tank is pushing it, I suggest a nice simple shrimp only tank. With a nice carpet of some kind, either christmas moss or flame moss for a lower light system, dwarf hairgrass or HC for a more medium to higher light system. Then have a nice tallish plant that will eventually grow up and drap over the top of the tank, like corkscrew val, something like that.
