Dart fish darting on sand

[Dami2205]

I catch My purple dart fish darting at the sand!!!! I check him out closely but I dont see signs of ICH or anything like that I also check the rest they all look fine. I just looked at him right now and its not doing it. Does anybody know if its like a normal behavior or should I start to worry!!!???

how long have you had it? any other fish showing signs of distress ?

 

[Dami2205]

Its not really distress since he did it a couple of times and then stop looked more of a territorial display, the rest are ok
