I think we all want our fish to have personality, it's just a case of what one person finds appealing the next person doesn't.... We don't all like the same women

I have 5 Festae at the moment they are only around 2-1/2" at most, so i can't really comment on their personality too much. They will obviously change alot in time, alot of people i have asked have said that theirs didn't really display much personality either. Mine are already eating out of my hand (Like a school of piranha lol) and are very responsive. I understand that they are small and things could change, but i will reserve judgement until i have given them some time
I have a few different setups, i also have a jack dempsey that has as much personality as my kids Oscars. He is always the first to the front of the tank, will follow your finger everywhere and never hides. Despite lots of peoples experiences with them being very shy.
This is 100% true
I have just aquired 2 Breidohri too, they are very interesting to watch, and look like they could have tons of personality but i have only had them a short while.
Each fish can and will display individual personality, i suppose it just depends on what you as the owner are looking for.
