Masstick is a blend of diverse all natural self-production highly technical compounds providing natural and balanced nutrition for omnivorous fish and marine invertebrates.
Masstick is comprised of raw materials of marine origin. It does not contain attractants artificial preservatives or synthesis products.

Masstick is a self-adhesive paste in a powder formula ready for rehydration with water.

Once rehydrated it can be stuck to any surface of the aquarium depending on the animals’ needs.

The rehydratable powder formula allows Masstick to be blended with any mollusc or crustacean pulp as well as eggs from fish molluscs and crustaceans artemia mysids copepods rotifers and medicines that are administered orally.

Once prepared and introduced into the aquarium Masstick does not disperse into the water for hours so it can be completely taken advantage of by fish and crustaceans.

This feature allows the product to be used as “ad lib” or rationed feeding.

Because Masstick is comprised mainly of freeze-dried crustaceans it does not contain fish skeletons and is thus very low in phosphates compared to its protein content.



Add Masstick to reverse osmosis water in a 1 to 0.5 ratio.


Example: Mix 14 g. of Masstick with 7 ml. of osmosis water. Knead in small ziplock bag until a homogenous mixture is obtained.

Once the mixture is homogenous Masstick may be used immediately or frozen for later use.

If freezing Masstick it should be used within five weeks after preparation.


Instructions for use:

Take a portion of Masstick and stick it on a rock a branched coral skeleton or the aquarium glass (preferably on the lower third) or depending on the food-obtaining habits of the animals in the aquarium.



  • Masstick 14 contains one transparent zip-lock bag with 14 net grams netos of product.
  • Masstick 42 contains three transparent zip-lock bags with 42 net grams of product in each one.
  • Masstick 70 contains five transparent zip-lock bags with 70 net grams of product in each one.


Product characteristics

Masstick is made with the freshest and highest quality ingredients.

The blend consists mainly of shrimp (Palaemonetes varians) that we produce ourselves harvested in the “Veta La Palma” Natural Space and which are immediately freeze-dried to maintain optimum nutritional value.

Freeze-dried microalgae and macroalgae are also added to the blend to satisfy the nutritional needs of a wide variety of marine fish.

Masstick provides an essential source of proteins lipids rich in fatty acids EPA ARA and DHA vitamins and carbohydrates from natural sources of marine origin.

The value chain is controlled and supervised by our technical and scientific personnel.

This guarantees the highest quality product.

Dietary needs vary among carnivores omnivores and herbivores and also depend on the animal’s feeding habits at the surface middle or in deep waters.

It is difficult to find feed that meets all nutritional needs in the way each species prefers.

With Masstick we have met these unique requirements.


Masstick’s formula naturally attracts finicky fish who begin eating it immediately or shortly after it is introduced in the aquarium.

Masstick is easy to use and comes in sealed bags with an oxygen and light barrier to preserve its freshness.


Nutritional profile:


Masstick’s nutritional profile has not been formulated to satisfy the needs of individual species but to reduce deviations to a minimum and as such it is an intermediate feed that satisfies the needs of the majority of aquarium species.

As shown in the table Masstick has a very low humidity content for improved preservation of the product.

Humidity content affects the chemical and physical properties of foods related to freshness and stability in terms of storage during long periods of time.

Freeze-drying (lyophilisation) and sealed packaging reduces water content to a minimum.

Proteins are necessary for normal functions including enzymes hormones and antibodies.

Protein is the most important part of the diets of fish and carnivorous coral.

Protein content of Masstick is very high and completely of marine origin.

Proteins are large complex molecules made up of various amino acids that are essential components in the structure and functioning of all living organisms.

The first need regarding protein requirements of fish is to supply the indispensable amino acid requirement of the animal and secondly to supply dispensable amino acids or sufficient amino nitrogen to enable their synthesis (Macartney 1996).

Lipids are an important source of energy and fatty acids that are essential for the growth and survival of fish and corals.

Although fish have low energy demand and are therefore susceptible to deposition of excessive lipid (Earle 1995) lipids do have a role as carriers for fat-soluble vitamins and are important in the structure of biological membranes.


As such Masstick does not contain a large amount of lipids but is richer in long chain fatty acids like DHA EPA and Arachidonic acid. Marine fish are incapable of biosynthesising DHA either new or from shorter chain acids like linoleic acid (Sargent 1997 1996).

Deficiencies in fatty acids can affect fish nutrition depigmentation skin survival and reduce feeding efficiency.


Carbohydrates are not an essential part of the fish diet. However if a small amount of carbohydrates is not provided in the diet other nutrients like proteins and lipids are catabolised as energy to provide the intermediate metabolites for the synthesis of other biologically important compounds.

High content of carbohydrates is inappropriate in a fish diet and as such it is important to provide the optimum amount of carbohydrates. A balanced amount of carbohydrates is included in the Masstick blend.

The content of dietary fibre (non-digestible carbohydrates) is low in Masstick.

Vitamins are essential elements in the diet of each fish. They are compounds that are produced naturally in the environment and in many cases cannot be synthesised by the animal.

As such vitamins should be supplied through dietary means.

Vitamins are generally destroyed during the manufacturing process and must be added to the food afterwards.

In the case of Masstick our manufacturing process (freeze-drying or lyophilisation) allows the natural vitamins to be present in large quantities within the blend without the need to add any type of synthetic vitamins.


Ash content in Masstick is slightly higher than in other fish feed. This ash is the inorganic residual left after the water and organic material have been removed (not crude ash) which provides a part of the total quantity of minerals in a food substance.


The nutritional profile of lyophilised Palaemonetes varians the main component of Masstick is very similar to that of live mysids or shortly after death making it particularly adequate for fish feed.
