OPTIMUM HIGH NUTRITIOUS FOOD 100 GRAMS

Optimum High Nutritious Food is a 100 gram general-purpose staple fish food built around a broad, balanced nutritional profile for everyday feeding of common ornamental fish, rather than being tuned to any single species or life stage.

"High nutritious" formulas like this typically combine fish meal or similar protein sources with plant material, vitamins, and minerals to support overall health, colour, and immune function across a mixed community tank, functioning as a reliable everyday base diet. Checking the ingredient list for a named fish or shrimp meal near the top, rather than generic "fish by-product" or heavy filler content, is a reasonable quick way to judge quality when comparing between similar general staple foods.

It's the kind of food that suits the bulk of a community tank's day-to-day feeding, complemented occasionally by a more specialised or protein-rich treat for variety.

Being a general-purpose formula rather than a species-specific one, its main advantage is simplifying feeding across a tank that holds several different fish at once — rather than sourcing a separate specialist food for each species, one reliable staple covers the everyday nutritional needs of most common community fish sharing the same water. That broad-spectrum approach is also what makes it a sensible starting point for a newer keeper still building up their collection of species-specific foods.

Feed small amounts once or twice a day, only what fish consume within a couple of minutes — as with any staple food, uneaten leftovers sinking and decomposing is one of the most common causes of declining water quality.

Works well as the everyday base of a varied diet; for fish with more specific needs (bottom feeders, fry, specialist carnivores or herbivores), it's best supplemented rather than relied on exclusively. A community tank mixing genuinely different feeding types — say a surface feeder alongside a bottom-dwelling scavenger — will still get more complete nutrition from occasional targeted supplementary feeding for each.

Store in a sealed container away from humidity and direct light — general staple foods lose nutritional potency and can develop a stale smell over time once opened and repeatedly exposed to air.

At this 100g size, most community tanks will work through the pack at a reasonable pace, but it's still worth checking the container periodically for clumping or an off smell in a slower-feeding tank, both signs that moisture or age have started affecting the food before it's finished. Feed at roughly the same time each day where practical, since a consistent routine makes it easier to notice a genuine appetite change (an early sign of illness) against a normal baseline.

As a general staple, consistent portioning and freshness matter more than any single feeding choice:

• Feeding amount: only what's cleared in 1–2 minutes, once or twice daily
• Best suited for: general community omnivores as an everyday base diet
• Storage: sealed, cool, dry, away from direct sunlight
• Shelf life: use within a few months of opening for best nutritional value
• Mixed tanks: a broad-spectrum formula like this covers most common omnivorous community species at once, simplifying feeding across several fish sharing the same water
• Watch for overfeeding: uneaten food sinking and decomposing is a common, avoidable cause of poor water quality
• Variety: pairs well with an occasional protein-rich treat (frozen or freeze-dried bloodworm/brine shrimp) for a more varied, balanced diet
• Format: typically supplied as flake or small pellet, suited to surface and mid-water feeders across a mixed community tank
• Ingredient check: a named fish or shrimp meal near the top of the ingredient list is a reasonable quick indicator of overall quality
• Consistent timing: feeding at roughly the same time daily helps you notice a genuine appetite change early, against a normal baseline
• Container check: discard if the food clumps, smells off, or shows signs of moisture damage, even within the stated shelf life
