I have a saltwater nano Im starting and a 37 gallon freshwater planted tank with a Fluval C02 system.
Make sure you have alot of money, lol. And do your research.
8 different freshwater varieties.
Just got into the hobby since I was a kid. Have a son of my own now and did this because I figured he would like to look at the fish. Turned into a weird obsession for me.

Modern advances in technology affect every industry - even the aquarium hobby.
If you are looking for a unique invertebrate to add to your saltwater tank, consider the sea urchin.
