In the world of poker, players come in all types—each with unique behaviors, strategies, and skill levels. Among these, two terms are frequently used to identify inexperienced or weaker players at the table: donkey and fish. While they’re sometimes used interchangeably, each label represents distinct characteristics. Understanding the difference between a donkey and a fish can be crucial for serious poker players who seek to sharpen their edge and maximize profits.
This article delves into the nuanced distinctions between donkeys and fish, offering strategic insights on how to spot each type and most importantly, how to adjust your gameplay accordingly.
What is a Fish in Poker?
A fish in poker is a player who is relatively new to the game and lacks the fundamental skills necessary to be profitable in the long-run. Fish are often unaware of proper hand values, pot odds, positional advantages, and betting strategies. Unlike experienced players, they tend to make calls in situations where folding or raising would be more appropriate.
Key identifying traits of a poker fish include:
- Consistent calling regardless of position or hand strength
- A lack of understanding of pot odds and implied odds
- Chasing draws with improper odds
- Overplaying mediocre hands
- Rarely bluffing or doing so inappropriately
Fish often participate in low-stakes games and are generally passive, making them easier to beat over long sessions. However, they can also be unpredictable, which can occasionally lead to unexpected wins.

What is a Donkey in Poker?
The term donkey (or donk) is a bit more derogatory and is used to describe a player who not only lacks skills but also exhibits reckless or irrational behavior. Donkeys may appear more aggressive than fish, frequently making bizarre bets, ill-timed raises, or calling down opponents with clearly losing hands.
Common characteristics of a poker donkey include:
- Random aggression without a strategic foundation
- Overconfidence despite regularly losing hands
- Ignoring position entirely during play
- Making unconventional plays that defy poker logic
- Donk bets — leading into the pre-flop raiser with weak holdings
Unexpectedly, some donkeys may even have a decent understanding of the rules but sabotage their own game with ego-driven plays or emotional decisions. This makes donkeys less predictable and far more erratic than your typical fish.
Donkey vs. Fish: Key Differences
While both terms describe exploitable players, it’s important to appreciate their differences. This will allow you to tailor your strategy for each type and capitalize on their weaknesses more effectively.
Trait | Fish | Donkey |
---|---|---|
Knowledge Level | Low or beginner | Varies, sometimes knows rules but makes poor choices |
Common Playstyle | Passive and overly cautious | Overly aggressive or erratic |
Emotional Control | Unaware of poker psychology | Often lets ego dictate decisions |
Predictability | Somewhat predictable | Unpredictable and irrational |
Strategy Used | Lack of strategy | Illogical or misunderstood strategy |
How to Exploit Fish
Playing against fish is generally straightforward once you’ve identified them. These players are your bread and butter in low-stakes games, and the key to winning big is a patient, value-oriented approach.
Here are a few tips for maximizing profit against fish:
- Play tight-aggressive: Stick to strong starting hands and bet them confidently when ahead.
- Target weak spots: Exploit their tendency to call too often by value betting more than you would against a regular opponent.
- Avoid bluffing: Bluffing a fish often backfires because they’re inclined to call with mediocre hands.
- Control the pot size: Use your positional advantage to keep pots manageable when needed and escalate them when your edge is strong.
Over time, disciplined play against fish will yield positive long-term results. These players often don’t notice patterns, so you can repeatedly apply the same techniques without adjustment.
How to Handle Donkeys
Donkeys require a more careful touch. Since they often lack logic and predictability, trying to outplay them using conventional strategies can blow back. Instead, focus on maintaining psychological control and capitalizing when they make egregious errors.
- Stay calm: Donkeys thrive on chaos; don’t let erratic behavior lure you into their territory.
- Wait for big hands: Let them hang themselves—donkeys will often donate chips when you patiently trap with strong holdings.
- Don’t fight fire with fire: Avoid matching their aggression unless you’re clearly ahead in the hand.
- Observe and adapt: Some donkeys exhibit patterns, even if irrational. Track their behavior and exploit recurring mistakes.

Why Knowing the Difference Matters
Mistaking a donkey for a fish—or the other way around—can lead to costly errors in strategy. While both types hemorrhage money over time, how they lose it and how you should engage them differs significantly.
Fish lose money by being passive and oblivious to value plays. You can methodically pick them apart with classic ABC poker. Donkeys, on the other hand, spew chips erratically, often punishing tight or passive opponents who fail to adapt. Trying to bluff a fish rarely works; trying to trap an erratic donkey without proper backing is equally dangerous.
The Evolution of These Archetypes
The poker landscape is always evolving. With the proliferation of online tutorials, free tools, and real-time game analysis, the traditional definitions of donkeys and fish have blurred. However, even in today’s more educated poker environment, novice players and emotionally driven opponents still populate tables, especially at the lower stakes.
Understanding these player types and fine-tuning your approach to each remains a cornerstone of successful poker strategy in both online and live settings.
Final Thoughts
Recognizing and adapting to opponent archetypes is a critical aspect of becoming a strong poker player. Fish offer a steady drip of profit through poor calls and misunderstandings of the game. Donkeys present a more volatile challenge but one that can be equally, if not more, lucrative when approached wisely.
In your next session, pay close attention to your opponents. Watch how they bet, how they react to aggression, and how they handle losses. Are they calling down with bottom pair? Playing every hand like it’s a bluff-athon? You may have spotted a fish—or a donkey—and your game plan should shift accordingly.
As the old poker adage goes: If you can’t spot the fish at the table in the first 30 minutes, you are the fish. But now, with a deeper understanding, you’ll also be able to spot the donkey—and know exactly what to do when you find one.
