Ultra Tropical Fish Flakes 100g

Ultra Tropical Fish Flakes — Premium Protein Supplement for Isopods, Millipedes & Snails

A super premium, insect-based, high-protein flake food originally formulated for tropical fish — and one of the best protein supplements you can offer to isopods, millipedes, snails, and other invertebrates. The rich blend of insect meal, shrimp, herring meal, and salmon oil provides the kind of dense, easily digestible protein that detritivores need for healthy growth, strong moulting, and consistent breeding.

100g resealable bag — a small amount goes a long way for invertebrate feeding.

Why Fish Flakes for Invertebrates?

Experienced isopod and millipede keepers have used high-quality fish flakes as a protein source for years, and for good reason. Detritivorous invertebrates need protein for growth, moulting, and reproduction — but in the wild, they get this from a varied diet of decaying organic matter, dead insects, fungi, and biofilms. In captivity, you need to actively supplement protein, and fish flakes are one of the most efficient ways to do it.

This particular blend stands out from generic fish food for several reasons:

Insect meal as the protein base. Most cheap fish flakes use generic fish meal as their protein source. This formula replaces it with insect meal, fish hydrolysate, herring meal, and brewer's yeast — all higher-quality protein sources that more closely match what invertebrates would consume in the wild. Insect meal in particular is biologically appropriate for detritivores.

46.2% crude protein. Significantly higher than standard fish flakes. For invertebrates, this means a small amount goes a long way — you only need to offer pinches at a time, and your isopods will respond enthusiastically.

Omega-3, Omega-6, and Omega-9 fatty acids. Important for healthy moulting and shell development in isopods and shell maintenance in snails. The 0.84% Omega-3, 1% Omega-6, and 2.23% Omega-9 content provides a balanced fatty acid profile.

Spirulina, garlic, paprika, and curcuma. Natural ingredients that contribute colour-enhancing properties and broad-spectrum nutrition. Some keepers report more vibrant colouration in colour-morph isopods after switching to high-quality protein supplements like this one.

Wide vitamin and amino acid range. The full nutritional spectrum (Vitamin A, D3, E, C, lysine, methionine, betaine, beta-glucan, etc.) means this isn't just a protein hit — it's a complete supplementary food.

Which Invertebrates Benefit?

Isopods. All species in our isopod collection benefit from regular protein supplementation. Demanding species like Cubaris and Ardentiella particularly need consistent protein for healthy moulting and breeding — losing animals to moulting failure from protein deficiency is a real and avoidable risk in expensive colonies. Hardier species like Porcellio scaber and Giant Orange (P. laevis) show stronger breeding response with regular protein supplementation.

Millipedes. Larger species in our millipede collection — Chocolate Millipedes, Ghana Speckled Leg, and other giants — appreciate occasional protein offerings. Most millipedes are primarily detritivores, but a small amount of fish flake once a week supports growth and reproduction.

Snails. Both Rodatzi GALS and Pink Lipped Panthera benefit from protein supplementation 1–2 times weekly. Unicorn Snails and other small species can also be offered tiny amounts.

Springtails. Springtail cultures respond strongly to protein-rich foods. Crushed flakes added to substrate boost springtail population growth significantly — useful when establishing new cultures or boosting existing ones.

Cockroaches. Species in our cockroach collection are omnivorous and readily consume fish flakes as part of a varied diet.

How to Feed

For isopods: Crush a small pinch of flakes between your fingers and scatter on the substrate or place on a small dish. A pinch is enough for a colony of 20–30 isopods. Offer 2–3 times per week. Don't overfeed — uneaten protein in humid enclosures spoils quickly and attracts mites and fruit flies.

For millipedes: Place a small amount on a flat surface near where they're active. Offer once per week as a supplement to their primary leaf litter and rotting wood diet.

For snails: Crumble a small amount and place on the substrate or mix into a vegetable serving. Offer 1–2 times per week.

For springtails: Sprinkle a small pinch directly onto the substrate. Springtails will rapidly colonise and break down the flakes, which both feeds them and accelerates substrate microbiome development.

General principle: Less is more. A small pinch is enough — these flakes are dense and concentrated. Overfeeding causes mould and pest issues that can damage the entire enclosure. Better to offer small amounts more frequently than large amounts that go uneaten.

Storage

Store the bag sealed and in a cool, dry place. Fish flakes can absorb moisture and develop mould if left open in humid environments. The 100g size will typically last several months for a small invertebrate collection — protein is offered in tiny amounts compared to fish feeding, so the bag goes much further.
