They are beautiful!
They will figure out where they like to perk and rest and such.
The two I keep are incredible social in the late evening. Actually they start with playing in the early evening, chasing/dancing & finding food together. They put their jaw against the LR and shake their bodies wildly and apparently love to do it. After all that they become increasingly social and play everywhere all over again and this kind of just climb in general comfort until the light go off.
I try to be in the room constantly or watching them through the door from the next room. They can see me for hours everyday so they can get used to me.
Remember to have some nice offering of food every time you are cleaning or otherwise disturbing their tank, and just make them associate you with food-droppings. In the long run, it will become sad if they react to you as a "turf-invader"
The two I keep, arrived 25 days ago and they swim around after my hand in the tank to see when food will drop and are beginning to swim around my fingers to grab it when it comes.
Remember they are scared but VERY brave.
Their instincts will tell them to be brave, so just go gently with them and reward them for trusting you
Oh, they will ofc throw up sand sometimes.
They can do it for play, they sometimes do it to chase away things that scare them.
They also make noise, the females mostly make a hard BoB-ish sound, this is territorial and meant to chase away stuff, the males also make more clicking sounds that I would say are slightly similar to the clicking way that ferrets sound.
..gotta love these fishes
