14 Best Freshwater Fish for 29 Gallon Tank: A Useful Guide

Hey there, fish enthusiast! So you’re the proud owner of a 29-gallon tank, eh? Excellent choice, my friend! This size hits the sweet spot between “My fish have no room to swim” and “I might as well convert my living room into an aquarium.” So now comes the fun part—deciding on the freshwater fish for your 29-gallon tank. Let’s dive right into it, shall we?


How Many Fish in a 29-Gallon Tank? 

Before you start googling every fish species under the sun, you need to know how many finned buddies your tank can handle. A good rule of thumb is one inch of fish per gallon, but let’s get more specific:

– Small Fish (1-2 inches): You could go up to 29, but let’s aim for 20-25 to give them room to breathe, shall we?

– Medium Fish (2-3 inches): Around 15-18 should do the trick.

– Large Fish (3-5 inches): Limit these to about 7-10, as these big guys like their space.


How To Set up a 29-gallon Tank for Keeping Many Different Fish?

Before your finned buddies move in, you’ve got some prepping to do:

1. Filtration: Go for a hang-on-back or canister filter. Trust me, it’s worth it.


2. Heating: A heater is a must unless you’re getting Arctic fish, which—spoiler alert—you’re probably not.


3. Substrate: Choose between gravel or sand based on your fish’s natural habitat.


4. Decor: You’ve got room for creativity. Think rocks, caves, and plants. Maybe even throw in a pirate ship because… why not?


5. Water Parameters: A water test kit is a must. We’re talking pH, ammonia, nitrites, and nitrates here.
