I always start a tank with one or 2 tiger cucumbers, And they split. They hide in the day. And turn into a worm factory at night.
I also have yellow coris wrasse. 6 to be exact. They dive bomb and dig in the sand to go to sleep every night.
All you people that don't do something out of fear because some people had a bad experience. Keep fearing, keep wondering.
Everyone said Salt water is so hard. That's all I heard growing up. All I heard while looking to buy at the fish store where I started. You know what? It's pretty simple. More repetitive than anything.
