are charming, goofy, bottom dwelling community members that clean up leftover food, as well as stirring up mulm to keep your substrate clear.
They’re non aggressive, unfussy eaters and can provide your tank with a unique piece of clumsy charisma. The Corydora breed has eight main lineages, with hundreds of kinds of corys in each lineage. Corys will only breed and shoal with other corys in their lineage, such as Bronze corydoras with Venezuelan Orange corydoras, or Adolfoi corys with panda corys. However mixing two different types of corydora from the same lineage isn’t recommended, as cross breeding can muddy the quality of the fry.
Corydoras thrive in a school of at least six, resulting in a recommended tank size of minimum 65 liters for a group - however some smaller breeds, such as pygmy corys, can be kept in smaller tanks. Due to their sensitive whiskers, Corydoras prefer a softer substrate, ideally sand or aquasoil, as sharp rocks and gravel can cause injury. Recently Corydoras have boomed in popularity, resulting in a considerable price drop - making the exotic species more accessible.

Corydora fry are easy to raise, and the adults often lay eggs even when in community tanks, making them an ideal species for the beginner fish breeder. Their diversity of price and availability also make them a considerable option for experienced and professional breeders, as some exotic rarer corys can reach up to and past four hundred dollars, while the more common and typical corys, such as Bronze Corydoras, can range as low as ten dollars each. If you have any questions about corydoras, raising corydoras, or breeding corydoras, feel free to come in and ask our staff, or explore our diverse range of corys - from your cheaper corys to your exotic wild types!

20% off all frozen foods, just this weekend! Similar to humans, fish thrive on a diverse diet. One of the most popular ways to vary your fishes food intake is to introduce . Feeding frozen food to your fish twice or thrice a week can improve their colour, promote natural behaviours and provide them with beneficial nutrients - encouraging better digestion and long term health. Frozen foods can come in a range of different types, from brine shrimp, to bloodworms, to mixed diets for saltwater fish. Deciding which food is right for you depends on your fish, personal preference, and whether your tank is saltwater or freshwater. If you need help in picking which type of frozen food, don't hesitate to come ask in-store. Some people even choose to have a combination of different frozen foods, such as and . Most aquarists choose to feed frozen foods by defrosting the food in tank water, before feeding it into their tank, generally with a turkey baster or a pipette. Come explore our new in-store range of frozen foods while stocks last!

While cycling a can bear substantial similarities to freshwater cycling, such as its necessity and process, it harbors a few key differences. For example, often takes longer and requires further testing of the water parameters, such as salinity. Both kinds of tanks must be fully cycled before the addition of fish in order to ensure a successful ecosystem. 

To start your cycle, you first have to introduce bacteria into your system. You can achieve this via adding live rock or live sand. Some commercial sources even offer bottled bacteria, however the state of said bacteria can be questionable, therefore, /sand is generally preferred. Many aquarists have their own strategies for adding ammonia to their tank, in order to kickstart the cycle. Some choose to add chopped fish pieces, fish food or even a dead prawn. 

After the addition of ammonia, continuous monitoring of ammonia, nitrite and nitrate levels through testing is necessary. When the cycle is working effectively, there should be an ammonia spike, which transfers to nitrite, and then finally nitrate. You can observe these changes through water tests, or alternatively, bring your water in store to be tested. These changes take place roughly ten or twelve days into the start of your tank, but don’t be discouraged if it takes longer. 

Cycling requires both patience and research, and can be the hardest part of establishing a marine system. If you encounter any problems or trouble, feel free to come down and ask our workers for any advice

Live rock is a cornerstone of biofiltration for many , providing a kickstart to dramatically accelerate the cycling of new tanks as well as introduce thriving colonies of beneficial bacteria to help filter and balance water parameters.

Struggling to cycle a tank is a battle that any aquarist can relate to, regardless of experience and strategy. However, adding water and substrate from an already-cycled tank can give the cycle a kick start. Live rocks are a wide-scope alternative to this strategy. By introducing already flourishing bacteria, you can fast track your tanks cycling, as well as provide it with improved biofiltration. 

While can introduce small pests, they also introduce a plethora of different creatures such as tiny corals, macroalgae, small sponges and to balance out your ecosystem and prevent issues. Hitchhikers like small crabs, starfish and shrimp (as seen above) can also come in from Live rocks, providing a petite and individually unique eco-diversity. Many reefers additionally choose Live rock for its distinctive appearance and aesthetic, often featuring colourful algae, which furthermore competes with and prevents pests from taking hold. 

Live rock supplies a wide biological range of helpful additions for both cycling and stabilising a system, as well as introducing fascinating and unique micro-life to your tank and providing distinctive appearances. It’s the perfect choice for any aquarist setting up a tank, in need of help to stabilise a tank, or looking to add biodiversity to an established system.
