Be patient.

Its a good idea to put a herd cardinal tetra or no? Maybe this can help?

Wont hurt. They will all get eaten though.

Piranhas are skittish in nature, especially youngsters. It took about a year before mine finally came out of his shell, but when he did, watch out!

Turn on room light too. Spend time in there with him. That’d be my new tv for a while!!

Some weeks later no difference..
Anyway one question more
This fish is in aquarium 110x45x50 (cm)
About 230liter .. can i pute one more rhom with split? For some time or is small?

Ive had my rhom for 2.5 years and still never comes out. I always have my hands in the tank so im ok with it lol.

That tank is pretty bright. Might try dimming it down some especially for a newly imported fish.
And make sure to keep the light on a timer. That regular schedule of on/off can help.
The biggest thing is time and patience.

Great looking Rhombus. Beautiful. Nice decently sized tank. Not much more advice on the light situation. Dim the light or use ambient room light. Or use a dimmer system so when the light comes on it's very dim and slowly becomes brighter similar to a sunrise. I purchased my fish recently and it is 6 inch long and 2 years old. It adjusted to the fluorescent light within a couple days. I only use one bulb not both so all I can think of is maybe your light intensity is too much.
