Building a Predator Tank From Scratch
Education Hub / Building a Predator Tank From Scratch Guide 21 — Setup Framework Building a Predator Tank From Scratch Setting up a tank for a predatory species - puffers, larger loaches, predatory cichlids and similar - involves a few extra considerations beyond a standard community tank, particularly around feeding. This guide walks through the framework from empty tank to established feeding routine. Step One — Research the Specific Species First "Predator tank" covers an enormous range of requirements - a dwarf puffer needs a fundamentally different setup to a... Read more...
Reading Shrimp Health
Education Hub / Reading Shrimp Health Guide 20 — Health & Husbandry Reading Shrimp Health — Signs to Watch For Shrimp communicate a great deal about their condition through color, behavior and the molting process - if you know what to look for. This guide covers how to tell normal shrimp activity from genuine warning signs. Why Shrimp Are Harder to "Read" Than Fish Fish keepers often rely on swimming behavior, fin position and breathing rate as health indicators. Shrimp lack some of these obvious signals, and much of their... Read more...
Common Snail Myths Debunked
Education Hub / Common Snail Myths Debunked Guide 19 — Myths & Misconceptions Common Snail Myths Debunked Aquarium snails have a reputation problem - much of it deserved in specific circumstances, and much of it overstated or applied too broadly. Here's a factual look at the most common claims. Why Snails Get a Bad Reputation Most negative snail reputations come from a single scenario: a small number of snails arrive unnoticed (often as hitchhikers on plants), conditions in the tank happen to favor them, and within weeks the keeper has...

Feeding Fry
Education Hub / Feeding Fry - Hatch to First Solid Foods Guide 18 — Breeding & Rearing Feeding Fry — From Hatch to First Solid Foods The first few weeks of a fish's life are the period where feeding mistakes have the biggest impact. This guide walks through what fry actually need at each stage, and when to introduce each type of live food. Why Fry Feeding Is Different Newly hatched fry are not simply small versions of adult fish. Their mouths are tiny - often well under a millimeter... Read more...
The Nitrogen Cycle
Education Hub / The Nitrogen Cycle Explained Guide 17 — Foundation Knowledge The Nitrogen Cycle Explained Almost every problem a new fish keeper runs into traces back to one thing: an aquarium that hasn't finished cycling. This guide explains exactly what the nitrogen cycle is, why it matters, and how to know when your tank is ready. What the Nitrogen Cycle Actually Is The nitrogen cycle is the biological process by which toxic waste produced by fish, invertebrates and decaying matter is converted into progressively less harmful compounds by naturally...

Beak & Shell Maintenance in Puffer Fish
Education Hub / Beak & Shell Maintenance in Puffer Fish Guide 16 — Health & Husbandry Beak & Shell Maintenance in Puffer Fish Unlike most aquarium fish, puffers have continuously growing teeth fused into a beak-like structure. Without the right feed, that beak can overgrow — with serious consequences. Here's what every puffer keeper should understand. Why Puffers Are Different Most fish have teeth that are replaced or worn down through normal feeding. Puffer-fish are unusual — their teeth are fused into four large plates forming a beak, and that... Read more...
Snail Population Control for Hobbyists
Education Hub / Snail Population Control for Hobbyists Guide 15 — Practical Help Snail Population Control for Hobbyists If you've gone from a handful of snails to what feels like hundreds seemingly overnight, you're not alone — and you're not doing anything wrong. Here's what's actually happening and what your options are. This Is Completely Normal Bladder snails and Malaysian Trumpet Snails are both prolific breeders by design — it's part of what makes them such reliable livestock for feed purposes. In a tank with no natural predators, a small... Read more...
Mineral Supported Systems
Education Hub / Understanding Mineral Support Guide 14 — Husbandry Standards Understanding Mineral Support "Mineral supported" is at the heart of how we breed everything at Jack's Aquatics — but what does it actually mean, and why does it make a measurable difference to the livestock you receive? What "Mineral Supported" Means Every water source has a different baseline mineral content — the dissolved calcium, magnesium and trace elements that invertebrates rely on for shell formation, molting and general physiological function. Tap water on its own is rarely optimized for... Read more...
Live Feed Rotations
Education Hub / Setting Up a Live Feed Rotation Guide 13 — Feeding Strategy Setting Up a Live Feed Rotation A single feed item, however good, rarely covers everything a predator or developing fish needs. This guide looks at how to combine snails, shrimp and cultures into a rotation that covers nutrition, enrichment and natural feeding behavior. Why Rotate at All In the wild, most predatory fish encounter a constantly changing mix of prey — different sizes, movement patterns, textures and nutritional profiles throughout the year. A single repeated feed... Read more...
Acclimating Live Aquatic Arrivals — A General Guide
Education Hub / Acclimating Live Aquatic Arrivals Guide 12 — General Knowledge Acclimating Live Aquatic Arrivals — A General Guide A practical look at settling new live arrivals into your aquarium — what actually matters, what's often overstated, and how your intended use changes what's needed. The Two Things That Actually Matter Acclimation is often discussed as a single rigid process, but in reality it comes down to two separate factors: temperature and water chemistry. How much attention each one needs depends entirely on what the animal is going into... Read more...

Ultimate Micro-worm Culture Care Guide
Education Hub / Microworm Culture Guide Guide 09 — Live Feed & Cultures Microworms — The Complete Culture & Feeding Guide Microworms are one of the most effective, accessible and reliable live foods available to UK aquarium keepers — yet most hobbyists have never used them. This guide covers everything you need to know. What Are Microworms? Microworms (Panagrellus redivivus) are free-living nematodes — microscopic, non-parasitic roundworms that measure approximately 1–2mm in length. Despite being commonly called worms they are not true worms at all, but a separate phylum of... Read more...
Malaysian Trumpet Snails — The Most Underrated Feeder in Predator Keeping
Education Hub/Malaysian Trumpet Snails Species Guide Malaysian Trumpet Snails — The Most Underrated Feeder in Predator Keeping Most predator keepers know bladder snails. Far fewer know that Malaysian Trumpet Snails offer a genuinely different — and in many cases superior — feeding experience for their livestock. What Are Malaysian Trumpet Snails? Melanoides Tuberculata — commonly known as Malaysian Trumpet Snails or MTS — are a freshwater snail species characterised by their elongated conical shell and burrowing behaviour. They are widely kept in planted aquariums as substrate aerators but are rarely... Read more...
Problem Solving
Problem Solving — Jack's Aquatics Education Hub/Problem Solving Guide 07 ProblemSolving Most aquarium problems don't appear suddenly — they build quietly. When something looks wrong, the biggest risk isn't the issue itself, it's reacting too fast without understanding the cause. First Rule — Pause Before Acting Before changing anything, ask: Did something change recently? Was something added, removed, or cleaned? Has feeding increased? Has maintenance changed? If the answer is yes — that's usually where the problem started. Common Problems & How to Respond Cloudy Water Likely Causes Bacterial bloom... Read more...
Tank Health & Maintenance
Tank Health & Maintenance — Jack's Aquatics Education Hub/Tank Health & Maintenance Guide 06 Tank Health &Maintenance Good maintenance isn't about doing more — it's about doing the right things, at the right time. Most tanks fail because they're maintained without understanding why. What "Healthy" Actually Looks Like A healthy tank isn't spotless. It usually has slight algae presence, stable (not perfect) parameters, predictable behaviour, consistent feeding response, and minimal sudden changes. Key PointProblems start when we try to force a tank to look "new" instead of letting it function... Read more...
Live Food & Snails
Live Food & Snails — Jack's Aquatics Education Hub/Live Food & Snails Guide 05 Live Food &Snails Used responsibly, live food and snails support natural behaviour, enrichment, and balanced ecosystems. Used carelessly, they can quickly destabilise a tank. Why Use Live Food? Encourages natural hunting and foraging behaviour Improves feeding response in picky or stressed fish Can support breeding and conditioning Often produces less immediate waste when eaten gradually ImportantLive food should support a varied diet, not replace it entirely, unless your species specifically requires it. Using Live Snails as... Read more...
Feeding & Nutrition
Feeding & Nutrition — Jack's Aquatics Education Hub/Feeding & Nutrition Guide 04 Feeding &Nutrition Overfeeding is one of the most common causes of algae, poor water quality, and livestock loss. Feeding should support the entire ecosystem — not just the fish you see. General Feeding Principles Feed small amounts, consistently Observe how quickly food is consumed Remove uneaten food where possible Adjust feeding based on tank size, stock, and filtration More food does not equal a healthier tank Rule of ThumbIf food isn't eaten within a few minutes, you're likely...

Stocking & Compatibility
Stocking & Compatibility — Jack's Aquatics Education Hub/Stocking & Compatibility Guide 03 Stocking &Compatibility Most aquarium problems don't come from equipment failure — they come from too many fish, added too quickly, or mixed without understanding behaviour. What Overstocked Really Means Overstocking is not just about fish size. A tank can be overstocked even when fish are small, water looks clear, tests appear fine, and filtration is powerful. Overstocking occurs when waste production exceeds biological processing, fish are stressed by crowding or territory loss, feeding increases faster than stability, or... Read more...
Tank Cycling
Tank Cycling Explained — Jack's Aquatics Education Hub Education Hub / Tank Cycling Explained Guide 02 Tank CyclingExplained Tank cycling is the biological foundation of every aquarium. Without it, even small amounts of waste can be lethal. Cycling is not optional. The Nitrogen Cycle Fish and food create waste (ammonia) Ammonia is toxic Beneficial bacteria convert ammonia → nitrite Nitrite is also toxic Another group of bacteria converts nitrite → nitrate Nitrate is removed via water changes and plant uptake Key PointA tank is considered "cycled" when ammonia and nitrite...
