Hi and Welcome! I myself am a newbie to the SW
world and have learned a great deal on this site.
Some of the things I have learned so far are when it comes to 10g tanks it is best to only have maybe 2 fish in it as the limit. Clowns are not good for a 10g as they can get big and require at least a 20-30g tank.
Inverts and soft corals would be fine as they produce very little waste and won't affect the bio-load as much...same with soft corals.
Anemones, not until your tank is at least 6 months old. The require pristine water conditions, plus it gives yo more time to get your "feet wet" in SW
so to speak before attempting them lol.
CUC, not really necessary but can be added. I am setting up a 10g Nano and will be adding small CUC to mine.
Other things that can be added to a 10g are...
- Sexy Shrimp
- Porcelain Crabs
- Pom Pom Crabs
- Hermit crabs
Just to name a few. You can also check out the Nano Reef boards
for some great information and assistance as you progress on.
Enjoy your journey into SW
....it is an exciting adventure.
