Hi, current owner of a 10g nano reef. Ro
unit is a must for smaller tanks, as well as staying on top of water changes. Also, in a 10g a skimmer is not needed in a 10g as regular water changes should work. Go with a aquaclear filter for the major filtration on it.
I would never stock as many as 4 fish in my tank, 3 maybe depending what they they are. Neon hints are my fave an a pair of them would be awesome. No clownfish, they need at least a 20g IMHO
. A firefighter is great idea also
I have a Pygmy wrasse in mine, a six line an all the research I did said it would be fine in a 10g and they little thing is all over the place, an because it's so active is why I'm upgrading my 10g
