Floating aquarium plants!

Floating aquarium plants, often with long decorative roots, are popular in many types of aquarium setups. With good reason! There are many advantages to keeping floating plants in your planted aquarium; although they may not always be ideal combined with plants that need a lot of light, they are a great addition to almost every setup and quite easy to keep. Keep reading for more information about keeping floating plants, why they are great and which species make a good choice!

Why keep floating plants?

    Hiding place – many popular fish species such as bettas, dwarf puffers, gourami and clown killifish occur naturally in darker waters and prefer a densely planted and shaded aquarium with plenty of hiding places. Floating plants provide shade and cover and the long roots help make your fish feel safe, which can help prevent stress. I like using floating plants in quarantine tanks for this exact reason! It’s not just adult fish that will make thankful use of floating plants; they are also a great place for tiny fry and dwarf shrimp to hide and forage. The most popular floating plant with long roots is Limnobium Laevigatum, also known as Amazon frogbit.

  • Easy to grow & low maintenance – many of us fishkeepers are plant enthousiasts but at the same time unfortunately lack the green thumb, time or money to set up a high-tech, high-maintenance aquascape with more difficult plant species. Easy plants that require no extra lighting, nutrients or Co2 such as Java fern, anubias and crypt species are Continue reading

Breeding aquarium snails

To most aquarists, purposely breeding snails sounds a bit silly. After all, they are considered an annoying pest by most of us! However, to this day, the dwarf puffer caresheet remains one of the most popular posts on Aquariadise. Freshwater and brackish puffer fish like dwarf puffers are a joy to keep, and their natural diet actually consists mostly of snails. While there are many other great food sources for a puffer, the hard snail shells are a good way to keep their constantly growing teeth short. And although dwarf puffers are the only species that don’t need snails for their teeth, there is nothing more fun than seeing them display their natural behavior by hunting a real, live snail.

Another popular aquarium inhabitant that feeds on snails is actually a snail itself; assassin snails are often used to control a snail plague. As many beginning (dwarf) puffer or assassin snail keeper will soon realize, though, snails are a bit harder to come by than you’d expect! One puffer can get rid of a snail plague in a matter of days (although this is not a good reason to buy them!), so Continue reading

Why betta bowls are bad

Even though awareness on betta fish care seems to be slowly spreading, both pet stores and the internet are still an enormous source of misinformation. Betta bowls, vases and ridiculously small “aquariums” are still sold on a large scale, which means many unfortunate bettas die a premature death due to bad housing. Don’t be fooled by their size – even though bettas are very small fish and often quite cheap, they still need to be kept in a heated, filtered aquarium to thrive.
Keep reading to see some of the most common betta myths smashed and find out just why a bowl, vase or very small tank is not enough to keep your betta healthy in.

Betta myths

Myth: Bettas in the wild live in small muddy puddles and even animal footprints. They like dirty water and small spaces.
False! While the water bettas live in sometimes seems muddy due to its darker color, it’s actually stained by plants and fallen leaves. They are not “used to” dirty water: a filter and water changes are necessary. Although the water is often quite shallow, the rice paddies and streams bettas naturally occur in are actually huge! Your betta will not “freak out” in a larger space. If it does, you should add more hiding places in the form of plants, rocks and decorations. Growing live plants can be intimidating, but luckily there are many beginner plants such as Java fern that help a betta feel safe.

Myth: Bettas can survive in vases eating plant roots.
False! Bettas are carnivorous surface feeders that mostly eat fallen insects. When kept in a vase with only plant roots to eat, a betta will starve. The plant roots may also block the surface, making it impossible for your betta to reach the surface to breathe! Breathing air is necessary for your betta to survive, so it should always be able to reach the surface.

Myth: An “aquaponics” system is a good way to keep a betta in a tiny container because the plants will remove wastes.
False! There is no excuse for keeping your betta in a very small unfiltered container. Proper aquaponics systems, where plants are grown on top of the aquarium using the wastes from the fish as fertilizer, can be a fun project. However, the tiny “aquaponics” tanks that seem to be all the rage because they claim to make water changes and cleaning unnecessary, are little more than Continue reading

Choosing an aquarium substrate!

There are many types of aquarium substrate to choose from nowadays; substrate choices range from neon colored gravel to all natural looking sand types. Because the substrate is an important place for beneficial bacteria to grow, using it is recommended in most cases. However, choosing the right substrate can be a bit of a challenge, because each type has a different effect on your aquarium and fish. Keep reading for a list of the most common aquarium substrate types and their pros and cons, which will hopefully help make the choice a bit easier!


Gravel is probably the most commonly used aquarium substrate. It’s available in many particle sizes and shapes and is often dyed in bright, artificial colors. There is a type of gravel for almost every setup – with a few exceptions.

Vacuum Cleaner

If you’re thinking of using gravel, consider your stock first! Be sure to check which substrate the fish you’re interested in will do best on. Some species, like Corydoras catfish, like to sift through the substrate to find their food. Gravel will make this quite difficult for them, and sharp gravel may even damage their delicate barbels and cause rot. Other aquarium fish, like Kuhli loaches, like to burrow into the substrate and have delicate bellies that may get damaged by sharp gravel. Using sand is not absolutely necessary for these species, but it will allow them to show their natural bevior. One species that should not be kept on gravel at all is the ever-popular goldfish; gravel can get stuck in their throat and you may end up having to take it out with a pair of tweezers, which obviously causes the fish a lot of stress.

Another point to keep in mind if you’re considering gravel, especially bigger sizes, is the fact that dirt particles and uneaten foods will be quite difficult to remove. They can build up and cause bad water quality when the gravel is disturbed after a longer time. If you do decide to go with gravel, especially with the fish species mentioned above, a smaller, polished type is probably your best bet! Natural colors will also be Continue reading

Fishkeeping on a budget

Aquarium keeping is a notoriously expensive hobby. Contrary to what some beginners think, you don’t just need a fish tank to get started – you also need a filter, heater, substrate, fish food, water conditioner, a backup fund for medication and endless other small necessities. This can really drive up the costs, which is definitely not what you want if you’re someone with a smaller budget (or a student like me!). Luckily, though, there are a few things you can do to reduce the costs of getting started and keep the electricity bill down. The most effective tips are listed below!

Buy used

The single most effective trick to keep the cost of setting up an aquarium down is to buy used. There are plenty of sites where you can buy everything you need for prices that are much lower than those at actual aquarium stores. The price of a used, good quality non-damaged aquarium is usually less than half of the store price; even when it’s as good as new. Filter, heater and extras like fish food, air stones and leftover medication are often included for a very low price or for free.
To make sure you’re not buying a damaged aquarium, Continue reading

Feeding goldfish

Feeding (fancy) goldfish seems simple: you buy some fish flakes and you’re all set, right? As with many things in the aquarium world, it’s unfortunately a little more complicated. Traditional fish flakes, while marketed as such, are almost never suitable goldfish food. They usually contain fillers that barely have nutritional value and can actually be bad for your goldie’s health. So what is a proper diet for a goldfish? Keep reading for more info on what to feed them and what not to feed them.

The most important thing to remember when it comes to goldfish diet is that variety is key. Goldfish are omnivores; although their diet should be vegetable based they need protein to prevent nutrient deficiencies. Because they are known to start begging for food as soon as someone walks into the room, it’s also important to make sure not to overfeed them! It’s tempting to feed large amounts, but goldfish are designed to spend the day “grazing”, which means Continue reading

How to hand feed your fish!

Teaching your (gold)fish to eat from your hand is not only possible; it’s also a fun experience and it can be very helpful for your fish to be used to your hands, for example when you need to examine possible injuries. It just takes some patience! Hand feeding is most popular among goldfish keepers, but there are other species that will also happily eat from your hand, like bettas.

Before you start attempting to hand feed your fish, make sure your hands are absolutely clean. There should be no traces of soap/cosmetic products. If you have unhealed cuts/lesions on your hands or fingers, stop hand feeding your fish or wear gloves! When dealing with more aggressive fish like bigger puffer species, consider feeding with plant tweezers instead of your fingers (just to be sure!).

Or try to eat your hand altogether! Photo by Goldfishdoctor.

To teach your fish to eat from your hand, patience is key. If the fish are already aware that you are the one that feeds them (for example, when they beg for food when you approach the tank), that’s one step in the right direction! They already associate you with a positive event. If this is not already the case, it’s a good idea to stay by the aquarium while the fish eat for a while.

To get the fish to also associate your hand with something positive, start off by feeding them and leaving your hand in the water while they eat. If they’re shy at first, just remove your hand after a while and try again later until they will happily feed with your hand near them. This way the fish will usually lose fear of your hands quite quickly! Once they do, you can start actually trying to hand feed them. Leave some food in your hands or between your fingers and be patient again while the fish adapt. The bravest fish will quickly realize they will be able to eat more if they eat from your hand, and do so happily. If you also want to be able to handle your fish, for example if you need to examine an illness, hand feeding is a great way to make them less scared of your hands. Just be sure not to touch your fish unless it’s absolutely necessary!

Note: You can now buy New Era goldfish food online here! My goldfish dealer recommended this food to me; he actually fed it to all his goldfish. It’s great to hand feed with because you can knead the pellets into bigger balls.

It’s as simple as that! If you keep hand feeding your fish regularly they will eventually get 100% used to your hands.
