What are frail fish?

[MisterBHomes]

I'm looking at some fish and some of them have "Frail" In their description

Fish have color, species, and gender that are pretty obvious. These are going to be important when breeding begins, obviously.

The other attributes you are wondering about include being Resilient, Hardy, (null), Frail, and Very Frail.

They will presumably pass these traits on when breeding is finally released in an update.

They are also Very Curious to Extremely Uninterested. Very Extroverted to Very Introverted.

I did a spreadsheet with these personality traits and a few others, and the illnesses as well. I don't know if the creators will change the odds on these but at this point it seems that a fish is as likely to be completely healthy as it is to have any one of the diseases. It can have no personality traits named, which means they are middlin' curious, not introverted or extroverted, etc. I have never seen a fish have more than 4 named attributes total. I have not seen one that is, say, Introverted and Extroverted, or Hardy and Frail. Usually they are what I call "dull" which means they don't have any outstanding feature beyond species, color, and gender.

I could explain this better but I'm pretty sick and my good keyboard was treated to a glass of milk, courtesy of the cat who loves spilling my drinks. This is like typing in handcuffs

Frail fish are more likely to get stressed, injured and sick.
