Kissing Gourami With Giant Gourami – Your Ultimate Guide To Tank

Written ByHoward Parker

Have you ever stood in front of a massive aquarium, mesmerized by the gentle giants gliding through the water? The thought of housing the iconic Kissing Gourami alongside the truly majestic Giant Gourami might feel like the ultimate aquarium dream. It’s a pairing of personality and presence that can be the centerpiece of any home.

But then, the questions start flooding in. Will they fight? Is my tank big enough? How can two such large and different fish possibly coexist peacefully? It’s a common worry, and one that stops many aquarists from even trying.

Imagine, though, a thriving aquatic world where these two titans live in harmony, their unique behaviors on full display. A tank that’s not just big, but balanced, healthy, and a source of endless fascination. You can achieve this.

Don’t worry—we’re here to show you how. This comprehensive guide will walk you through everything you need to know about keeping a kissing gourami with giant gourami, turning that ambitious dream into a stunning reality. Let’s dive in!

Meet the Contenders: A Tale of Two Gouramis

Before we can create a peaceful home, we need to truly understand the inhabitants. Think of it like getting to know two potential roommates. They have unique personalities, habits, and needs. Knowing them inside and out is the first step to success.

The Charming Kissing Gourami (Helostoma temminckii)

The Kissing Gourami is famous for one thing: its puckered-up “kiss.” But here’s a pro tip—this isn’t a sign of affection! It’s actually a test of strength between two fish, usually males, vying for dominance. It’s fascinating to watch, but it’s a clue to their semi-aggressive nature.

These fish can grow up to 12 inches (30 cm) in captivity, so they’re no small fry. They are omnivores with a special love for grazing on algae and biofilm, using their unique, toothy mouths to scrape surfaces clean. They are active, curious, and can be a real character in the right environment.

The Majestic Giant Gourami (Osphronemus goramy)

When we say giant, we mean giant. The Giant Gourami is one of the largest freshwater aquarium fish, capable of reaching a breathtaking 28 inches (70 cm)! They are intelligent, personable fish often described as having “water puppy” personalities. They can learn to recognize their owners and even be hand-fed.

Unlike their smaller cousin, Giant Gouramis are primarily herbivores. In the wild, they munch on aquatic plants, fruits, and other vegetation. This dietary preference is crucial to keeping them healthy and happy (and your aquascape intact!). Their calm, deliberate movements make them a truly zen-like centerpiece.

The Tank: Building a World Big Enough for Two Giants

This is where most aquarists make their first mistake. When keeping a kissing gourami with giant gourami, the tank isn’t just a glass box; it’s their entire world. And for these fish, that world needs to be massive. This is one of the most important kissing gourami with giant gourami best practices you can follow.

Tank Size is Non-Negotiable

Let’s be perfectly clear: you cannot keep these fish in a standard 55 or 75-gallon tank long-term. For a single adult Giant Gourami, the recommended minimum is 250 gallons. When you add an adult Kissing Gourami, you should be looking at 300 gallons (over 1100 liters) as an absolute starting point.

Why so big?

  • Territory: Both species can be territorial. A large footprint allows them to claim their own space, dramatically reducing squabbles.
  • Waste Load: Big fish produce a lot of waste. A larger volume of water dilutes toxins like ammonia and nitrite, creating a more stable, healthy environment.
  • Swimming Space: These are active fish that need room to turn around, explore, and swim freely without feeling cramped.

Filtration: The Unsung Hero

A huge tank needs a heroic filtration system. Your standard hang-on-back filter won’t cut it. You need a system that can handle the massive bioload these fish produce. Think of it as the life support system for your aquatic ecosystem.

We strongly recommend one of the following:

  1. Large Canister Filters: Consider running two large canister filters for redundancy and maximum water turnover. Aim to turn over the entire tank volume at least 4-6 times per hour.
  2. A Sump System: This is the gold standard for large aquariums. A sump adds a significant amount of water volume and allows you to hide heaters and other equipment, while also providing a massive space for biological and mechanical filter media.

Aquascaping for Peace and Harmony

How you decorate the tank is just as important as its size. A bare tank is a recipe for stress and aggression. Your goal is to create an environment with visual barriers and distinct zones.

Use large pieces of driftwood, smooth river stones, and slate to break up lines of sight. This allows a fish to retreat and feel secure, preventing constant confrontation. When it comes to plants, remember the Giant Gourami’s herbivorous appetite! Stick to tough, unpalatable options like:

  • Anubias (attached to wood or rocks)
  • Java Fern (also attached to decor)
  • Bolbitis
  • Large Crinum (Onion) Plants

The Ultimate Kissing Gourami with Giant Gourami Care Guide

With the environment set, let’s talk about day-to-day care. Following this kissing gourami with giant gourami care guide will ensure your fish don’t just survive, but truly thrive. Consistency is your best friend here.

Water Parameters: The Foundation of Health

Both species are quite hardy, but they appreciate stable, clean water. Don’t chase a perfect number on a test kit; focus on keeping the conditions consistent.

  • Temperature: 75-82°F (24-28°C)
  • pH: 6.5 – 7.8
  • Hardness: 5-20 dGH
  • Ammonia & Nitrite: 0 ppm (absolutely essential)
  • Nitrate: Below 40 ppm

A Diet Fit for Titans

Proper nutrition is key to health and peaceful coexistence. A hungry fish is often an aggressive fish. Since their diets differ, you’ll need to provide a varied menu.

For the Giant Gourami (mostly herbivore):

  • High-quality herbivore pellets or wafers as a staple.
  • Daily offerings of blanched vegetables like zucchini, spinach, kale, and shelled peas.
  • Occasional treats of fruit like banana or melon chunks.

For the Kissing Gourami (omnivore):

  • A quality omnivore pellet or flake.
  • They will happily share the vegetables offered to the Giant Gourami.
  • Supplement with frozen or live foods like bloodworms, brine shrimp, or earthworms a few times a week.

Routine Maintenance for a Thriving Ecosystem

In a large tank, maintenance is a marathon, not a sprint. A consistent schedule is crucial for a sustainable kissing gourami with giant gourami setup. This is how you create an eco-friendly kissing gourami with giant gourami system—by maintaining balance.

Plan for a 30-50% water change every single week. This is non-negotiable for removing nitrates and replenishing essential minerals. Use a gravel vacuum to clean a portion of the substrate with each change, and regularly rinse your filter media in old tank water (never tap water!).

Common Problems with Kissing Gourami with Giant Gourami (And How to Solve Them!)

Even with the best planning, you might encounter a few bumps in the road. Don’t panic! Here are some common problems and actionable solutions based on real experience.

Problem: One Fish is Constantly Bullying the Other!

This is the number one concern. If you see persistent chasing or “kissing” that seems aggressive, intervene.

Solution:

  1. Rearrange the Decor: A complete re-scape can reset territories and break the cycle of aggression.
  2. Add More Visual Barriers: If they can’t see each other across the tank, they are less likely to fight. Add a large piece of driftwood or a tall rock formation.
  3. Check Your Feeding: Ensure both fish are getting enough food. Sometimes aggression is just resource guarding.

Problem: My Giant Gourami is Destroying My Plants!

This is simply the nature of the beast. A Giant Gourami sees a tasty green snack, and it’s hard to blame them.

Solution:

  • Increase Veggies in Their Diet: A well-fed herbivore is less likely to graze on your aquascape. Offer blanched greens daily.
  • Stick to “Gourami-Proof” Plants: As mentioned before, Anubias and Java Fern have tough, waxy leaves that most fish find unappetizing.

Problem: The Water Quality is Poor Despite My Filter.

Cloudy water, high nitrates, or a bad smell are all red flags that your maintenance routine or filtration is not keeping up.

Solution:

  • Increase Water Change Volume/Frequency: You may need to do two 30% changes per week instead of one 50% change.
  • Upgrade Your Filtration: Your current filter might simply be underrated for the bioload. It might be time to add a second filter or upgrade to a larger model or a sump.
  • Reduce Feeding: Make sure you are not overfeeding. Only give what they can consume in a minute or two.

Frequently Asked Questions About Kissing Gourami with Giant Gourami

What is the minimum tank size for a kissing gourami with a giant gourami?

For fully grown adults, the absolute minimum we recommend is 300 gallons. Starting with a larger tank, such as 400+ gallons, will provide a much greater chance of long-term success and a more stable environment for these magnificent fish.

Are kissing gourami and giant gourami aggressive towards each other?

They can be. Kissing Gouramis are semi-aggressive and territorial. While Giant Gouramis are generally peaceful, they can defend themselves. Success depends entirely on providing them with enough space, visual barriers, and proper care to minimize stress and territorial disputes.

Can a beginner keep these two fish together?

This pairing is best suited for an intermediate to advanced aquarist. The sheer size of the required tank and the commitment to heavy-duty filtration and maintenance can be overwhelming for a beginner. It’s a fantastic goal to work towards, though!

What do I feed them to ensure they both get the right nutrition?

Variety is key! Provide a staple high-quality pellet for each (herbivore for the Giant, omnivore for the Kissing). Supplement heavily with blanched vegetables daily for both, and offer protein-rich frozen foods a few times a week for the Kissing Gourami.

Your Journey to a Gentle Giant Tank

Keeping a kissing gourami with giant gourami is undoubtedly a major commitment. It requires space, investment, and a dedication to consistent care. But the reward is a truly breathtaking aquarium with intelligent, personable fish that will be with you for many years.
