Overview Aquarium Fish Food

With all the different types of fish you can keep in an aquarium, it's pretty clear that there are a HUGE number of things you can feed your fish.

Oase Organix Fiskfoder, alla sorter | Fish Food, all types, Corydoras.Zone Aquatics<br>Copyright ©

There are fish that mainly eat algae and plants, so we need to feed them "green stuff". Others are carnivores so we need to give them a lot of "meaty stuff". There are also omnivores that each pretty much anything that passes by in the water or it can dig up from the substrate.

Another very specialized group are wood eaters that needs roots, and wood containing feed to thrive in our tanks.

We will have separate articles and videos for most kinds of food you can use for your fish. Some of them you can buy in the Local Fish Store (LFS), or the grocery store. Others you can collect your selves in the nature, or you culture or grow them yourselves.

N.B.

Some people, like Kristian, can't use Bloodworms (or any food that contains them) since they are very allergic to them!

Images are coming for every main type of food below.

Repashy Superfoods Akvariefiskfoder | Tropical Fish Food, Gel Premixes, 2 kg, 340 g, 85 g från | from Corydoras.Zone<br>Copyright © Kristian Adolfsson Sweden

This type of food consists of a power that you mix with boiling water, leave it to set. You then cut it into cubes/strips and feed it to your fish. It keeps in the fridge for a couple of days but you can also freeze and use it over several months.

You can also dry it and make a jerky-type fish food. Dry it in an oven or dehydrator at about 65°C (150 °F) for 8 to 12 hours or until it is completely dry.

Repashy Superfoods from USA

The dominating one in this group is Repashy. They usually come in:

  • 85 g (3 oz) jars

  • 340 g (12 oz) jars

They have the following types of foods:

  • For all Rainforest Species with mostly Black Soldier Fly Larvae Meal and  Krill Meal but also some fruits. It is called Igapó Explorer

Dajana Pets from Czechia

Dajana has 2 types:

  • BioGel Omni for Omnivores
  • BioGel Herbi for Herbivores

They come in 5 x 10 grams and maybe in 1 kilo bags.

Tropical from Poland

A third brand is Tropical that has 3 types of gel food:

  • Gel formula for Omnivorous fish
  • Gel formula for Herbivorous fish
  • Gel formula for Carnivorous fish

They come in a plastic jar with 3 bags of 35 g and gives about 300 grams of finished product.

Plants & Algae

There are lots of plants and algae products you can use for your Herbivore fish. Some you can buy in the shop, other you can grow your selves. The advantage of growing it is that there are no pesticides on them. We have wiped out whole spawns of Rineloricarias and Sturisomas by feeding them non organic lettuce!

  • Lettuce of all kinds: grow / buy (organic)
  • Peas & String peas: grow / buy (preferably organic)
  • Cucumber / Zucchini: grow / buy (preferably organic)
  • Spinach: grow / buy (preferably organic)
  • Sheets of Nori / Kelp Algae: buy
  • Spirulina, Kelp & Chlorella Powder: buy

Wood

Repashy Superfoods Morning Wood 85, 340 grams and 2 kg burk | jar, Xylivore (wood-eating plecos) aquarium fish food gel premix | akvariefiskfoder<br>Copyright ©

Some Plecos need wood in their diet to survive.

It can be provided by keeping roots and pieces of wood in your tanks. Make sure that they are soft wood and that you have several types of wood in there.

There is also a Repashy food called Morning Wood and some Algae based Pellets / Wafers that contains wood.

More to come.

"Probiotic" Food

Some food manufacturers add some additives to their fish food and add the "Probiotic" label to it.

Some of the things they add are:

  • Beneficial Bacteria
  • Garlic
  • Paprika

Will expand on this when we've looked more in to this type of food.

Fry Food

Oase Organix Baby Flakes Yngelfoder / Fiskfoder | Fry Fish Food, 150 ml / 60 g, 84100, (4010052841007), Corydoras.Zone<br>Copyright ©

This is not really a group of it's own. So many foods can be used for fry as long as it's very small.

Powdered fry food

GP Diets (Golden Pearl Spheres) is one of my favorites, but I also use Kelp, Chlorella or Spirulina Algae powder.

There are also foods from Sera like Sera Micron Nature, Protogen by Hobby, and Liquifry by Interpet.

Newly hatched brine shrimp

One of the best foods, hands down. If you don't hatch brine shrimp and breed fish, you must start now!

Paramecium and other infusoria

If you can get hold of a starter culture this is a great first food for the really small fry that can't take artemia from the start. Species like Rainbowfish, some Tetras and Barbs pretty much need this the first couple of days.

You can get a starter culture of Paramecium from us if you are in central Skåne in Sweden.

Worms

Walter / Micro / Banana Worms and Vinegar Eels are all perfect for the smallest fry.

Decapsulated Artemia

These are unhatched and shelled Artemia Eggs. They should be fed as they are and will float for a while. Perfect for tetras, rainbowfish etc. that feed at the surface.
