Good Morning and welcome,
A 10g is NOT hard. I’m not sure why people say that. Tanks are not “hard.” Livestock care IS hard or easy and that fluctuates with tank size and equipment choices.
A 10g IM Nuvo is a GREAT tank for a new hobbyist. A 20g IM Nuvo is better as the 20g has dual overflows (less chance of clogged overflows causing leaks) but will require more light and a powerhead (more money). I only run one return pump on my IM Nuvo 20 but I have to wonder if I could fit two back there at which point you wouldn’t need a powerhead.
Either tank requires: A good heater, ATO, and a good light; I suggest a Radion XR15 for the 10g and a Radion XR30 for the 20g.
Either of these tanks once fully matured around a year will require nothing more than water changes weekly- and you’re talking about a gallon or two. Not really a big deal.
Easy Livestock example lists for either:
A pair of clown fish and a bubble tip added after 6 months. Additional soft corals or possibly an LPS if you are feeding correctly and keeping up with water changes.
Rockflower anemone garden with porcelain crabs and sexy shrimp (ultra low maintenance).
Soft corals and possibly LPS (or two) with pistol shrimp and goby.
I have included a picture of my IM Nuvo 10g. Next to it is a 20g IM Nuvo (freshwater). The 10g required about 15 minutes of maintenance every 2 weeks. Because I kept stocking and feeding low, I seldom have to clean the glass and honestly don’t really do water changes.
