I have just updated this post...
Okay I will join in here too.
Here is my 1 gal pico
It has : Coralife 18 watt 9" fixture, 9 watts true actinic 9 watts 10,000 daylight
Mini filter that it came with
15 watt heater
1 crab
Orange Florida Ricordea, Pink Yuma Ricordea, blue shrooms, green star polyps, 3 different colors of zoas, feather duster
Some stuff was taken out of my 10 gal that had been running for the past 4 years. I kept the small frags and added some new stuff since then, the tank has been going for 4 months now, I do very minimal water top ups each day, water changes once a week.
I have had no issues with this little tank and quite like it.
Enjoy......
