<li> <strong>Daily Water Changes Are Best</strong>: Changing 30–50% of the water daily keeps water crystal clear, prevents ammonia buildup, and ensures discus thrive in a clean environment.</li>
</ul>



<ul class="wp-block-list">
<li> <strong>If You Can&#8217;t Change Water Daily</strong>: Avoid overfeeding and ensure you have a high-quality canister filter to break down waste efficiently.</li>
</ul>



<h2 class="wp-block-heading Headiing2"><strong>Beneficial Bacteria &amp; Filter Maintenance</strong></h2>



<ul class="wp-block-list">
<li><strong>Beneficial Bacteria Live in the Filter</strong>: Since discus tanks aren’t heavily planted, beneficial bacteria in your filter are responsible for breaking down harmful waste.</li>



<li><strong>Don’t Over-Clean Your Filter</strong>: If your filter gets dirty, rinse it in tank water, not fresh tap water—chlorine in tap water can kill beneficial bacteria</li>



<li><strong>Establishing Beneficial Bacteria Takes Time</strong>: It takes weeks for a new tank to develop a healthy bacterial colony, so avoid cleaning the filter too frequently.</li>
</ul>



<h2 class="wp-block-heading Headiing2"><strong>Substrate &amp; Decorations</strong></h2>



<p class="Heading2Paragraph">When setting up a discus fish tank, choosing the right substrate and decorations is important for both aesthetics and maintaining a stress-free environment for your fish.</p>

<li>❌ Can trap debris and cause ammonia buildup if not maintained properly.</li>
</ul>



<p class="Heading2Paragraph">💡 <strong>For Beginners</strong>: It&#8217;s best to avoid substrate altogether. While substrate does provide a surface for beneficial bacteria, if not maintained properly, it can trap waste and lead to poor water conditions.</p>



<p><strong>Decorations: Keep It Simple</strong></p>



<p class="paragraph">Discus fish prefer open swimming space, so avoid cluttering the tank with too many decorations.</p>



<ul class="wp-block-list">
<li><strong>Driftwood</strong> – Creates a natural look and can help lower pH slightly.</li>



<li><strong>Smooth Rocks</strong> – Can be used for aesthetics but avoid sharp edges.</li>



<li><strong>Live Plants (Optional)</strong> – If you choose plants, go for hardy options like Amazon swords, Anubias, or Java fern.</li>



<li><strong>Caves or Hiding Spots</strong> – Good for reducing stress, especially in community tanks.</li>
</ul>



<p>💡Avoid decorations with sharp edges, as discus fish are delicate and can injure themselves.</p>



<h2 class="wp-block-heading Headiing2"><strong>Heating &amp; Lighting</strong></h2>
