From my experience with fishing in FFXV the way you entice the fish is by doing short bursts of reeling in while moving the lure from left to right to get it moving. Once the fish bites make sure you get the QTE to hook the fish so you can start the reeling in process.
After you enter the reeling in phase slowly start to reel in the fish if you start to see the red and white flashing bar stop reeling in order to keep your line from snapping. If the bar tells you to move your left stick to the left or right make sure you do as such since it builds tension a lot if you fail to move your line. Also be sure to pay attention if the fish decides to jump in the water since it will prompt you for another QTE to keep the fish on the line. Repeat until you catch that fish!
And make sure you feed that cat!
The answer to this question is subjective based on your play style and "ability" to play the game. Daemon fights are built to be more difficult than daytime fights. A person's knowledge of the combat system and how to use their equipment becomes increasingly more important as the game goes on. However I can answer some direct points.
Will nighttime always be dangerous?
Yes, nighttime will always be a decently dangerous undertaking. It will always be more dangerous than day time. During the main story, the daemons become both stronger and greater in numbers. As your level up, and more importantly, spend your Ability Points, your party becomes drastically better at being able to handle the daemons however, so it becomes less of a problem than at the beginning of the game, by quite a large amount.
UPDATE: NO It appears the demons at night stay around the same level throughout the game. (Exception being the endgame chapter where its always night.) Even while in chapter 15 and im level 99, the demons still seem to be mostly around the mid 30's. There may be some unique exceptions, but I havent run into any.
Also, as is mentioned in the comments, you can unlock a set of headlights for the Regalia that lets you drive at night without running into any daemons.
Will the nighttime daemons continue to scale up in levels so that they're always stronger than me? Or will I eventually be on equal ground with them?
No, the daemons will not always be higher level than you. They tend to be higher level than the beasts during the day based on the chapter your on, but if you complete enough sidequests you can out level the daemons.

Chocobos in Final Fantasy XV
To start, you'll need to complete "A Behemoth Undertaking" to unlock the ability to rent Chocobos. This is a Hunter Quest located at Wiz's Chocobo Ranch. It isn't difficult nor is it required, but it does make other aspects of the game easier and unlocks the path to all that is "Kweh."
Summoning a Chocobo:
Completing "Friends of a Feather" side-quest (contracted by Wiz at his ranch) will give Noctis the "Chocobo Whistle." The Chocobo Whistle acts just like the Beast Whistle, except it summons a Chocobo to the player location if they have time remaining on a rental. All players in the party (whether they are temporary or otherwise) will be given a Chocobo to ride.
Chocobos cannot be summoned in:
Leveling your Chocobo
Chocobo's increase level by simply riding them for a set number minutes. Like the time tracking with the Regalia, time on a Chocobo does no reset once dismount but simply stops until you mount and ride again. However, ride times are in addition to the previous number of minutes as opposed to a total time on the Chocobo.
For example, the player must ride the Chocobo for 24 additional minutes after obtaining Level 8, to reach level 9.
The last, Level 10, is great for those Link-Strike savvy fighters looking to increase AP and EXP by raising the Finesse Grade quickly (every little bit helps, right?), or who just like the idea of mauling enemies with a giant yellow bird you can ride around upon.
In all, to reach Level 10, the player must ride a Chocobo for a total of 138 minutes while in motion and mounted. Additionally, the Chocobo stands to gain roughly 20 scale mph in speed and an additional 40 points in usable stamina. This is very helpful if you're looking to hit the races and get additional rewards, or get to places faster than walking but more distant by roadway.
Given the day / night cycle in Final Fantasy XV is 45 minutes, mathematically speaking the player could rent the Chocobo for 4 days, band the controller, and run in circles for about 2 hours and 20 minutes real-time to grab Level 10 easily (like the same trick for pushing Gladio's skill to Level 10). It's best to do this in an area that you know the party won't be attacked at any point because the Chocobo will buck Noctis when enemies appear and bolt away.
Chocobo Races
Your Chocobo can wear up to four medals at a time, each earned by competing in races or events at Wiz's Chocobo Ranch. Medals do nothing practical, they just provide eye-candy and facilitate some in-game fun.
Note that feeding a Chocobo foods that grant a Choco-buff do not apply during races or events. Leveling is important should you hope to compete and win because the player will rely on the raw stats of their Chocobo.
Races & Medals:
Noctis can race and compete in events at any point of the game, which at times may require the use of Umbra.
You may have noticed this listed started at #2. The first medal is the Replica Medal and is a default medal when "A Behemoth Undertaking" is turned in. This isn't an earned medal in the same sense as the other 8 but is a medal all the same.
The last Medal is the Jockey Master Medal and is a prize for winning all other medals.
