Fished Up Monsters

Will they always have the 3 !!! or are some actually rated as just another fish that will only have just 1 ! Im ready to board the Mhauru to catch noble ladys and just want to avoid that Oberon nm.

!!! : Monster, Non-Stackable fish
! : Stackable fish, rusty items, items (Coral Fragment, are there any other items?)

All monsters and large fish will have "!!!".

Also, if the message says something positive (you have a good feeling or something similar), this mean it's a monster.
When the message sounds negative (you have a terrible feeling or something similar), it's a large fish.
Messages that sounds "unsure" mean it could be a 50/50 chance of being a monster or a large fish.

In my experience I have found that monsters usually have !!! followed by a positive feeling.

Negative usually indicates a large fish- say ryugu titan, squid, gugrusaraus etc.

Noble ladies do not give !!! they just give one !

Ive seen the 3 statements that lead to a large fish and in this case its the bladefish in e.saruta and its always been with the 3 !!! which is nice.

There are a few more rusties but naming them off is not needed but ancient lumber Im not sure.

Ive fished up gil before, 1 gil and 100gil, rusty caps, torn cap in windy, cant remember if anything else other than subligars
