Thank you all for the comments!
Continuing with another my favorite
Tetras - veiltail Hyphessobrycon callistus callistus
Growing up, they are not much spectacular, but being adult they are attractive and beautiful
:
Thats one crop showing their typical feature the veil tail and fins elegancy
I got 9 of them and they just dont much visible between all other Discus, Rainbows, Tetras
But they zone the tank, and every male watching for his own territory very strictly
Only sometimes, some female, goes to cross that borders and coquette in front the dominant male
The other guys just jealous gaping
:
But dont forget they are the cousin of Piranha too
if you make them angry just see how they look......
