Question 1

How do I choose between Fine Pellets (1.25mm) and Medium Pellets (2.50mm)?

Accepted Answer

Choose the pellet size based on the mouth size and body length of your fish. Fine Pellets (1.25mm): appropriate for small to medium fish including all Tetras, Rasboras, Guppies, Endlers, Chili Rasboras, young Goldfish under 10cm body length, small Barbs and small Cichlids under 8cm. Medium Pellets (2.50mm): appropriate for adult Goldfish, Koi, Oscar, Flowerhorn, Cichlids over 10cm body length and other medium to large ornamental fish. The practical size test: if a fish picks up a pellet and immediately drops it or repeatedly struggles to swallow it, the pellet is too large — switch to Fine. A correctly sized pellet is consumed in one or two bites without struggling.

Question 2

Why is the 1KG pack significantly more economical than smaller packs?

Accepted Answer

The 1KG pack at Rs 499 works out to Rs 0.50 per gram — compared to Rs 0.89/g for the 100g pack, Rs 0.75/g for the 200g pack and Rs 0.70/g for the 500g pack. The 1KG format is therefore approximately 44% more economical per gram than the entry 100g pack. For fish keepers who feed multiple tanks daily or maintain large ponds, the savings over a year of purchasing are significant. The key to making the 1KG format work is the decant-and-reseal storage protocol: keeping the main bulk pack sealed except for weekly refills maintains freshness throughout the supply.

Question 3

How do I store a 1KG pack to keep it fresh throughout?

Accepted Answer

The correct protocol for a 1KG fish food pack: on first opening, immediately decant approximately one week of feeding supply into a small airtight container (any clean, sealable container works). Reseal the main 1KG pack tightly. Keep the weekly supply container near your tank for daily use. Once per week, open the main 1KG briefly, refill the weekly container and immediately reseal the main pack. This minimises cumulative air and humidity exposure to the bulk supply, extending freshness significantly beyond what would result from repeatedly opening the main pack daily. In Indian monsoon conditions, add a silica gel sachet to both containers.

Question 4

Can I use the Fine Pellets for all fish in a mixed community tank?

Accepted Answer

Yes — Fine Pellets (1.25mm) can be used as the single food for a mixed community tank where the largest fish are medium-sized (up to approximately 12cm body length). All fish in the community will accept Fine Pellets — larger fish simply consume more pellets per feeding to meet their nutritional needs. The only practical situation where the Fine pellet causes issues in a mixed tank is when there are very large fish (adult Koi, large Oscar, large Flowerhorn) — these fish may reject Fine pellets as insufficient volume per bite. For a mixed tank with both small community fish and large cichlids, feeding Fine pellets to the community and Medium pellets separately to the large fish is the ideal approach.

Question 5

How long will a 1KG pack last for my tank or pond?

Accepted Answer

Duration depends on tank or pond size and fish count. Approximate estimates at correct small-portion feeding: single community tank of 20–30 small fish (2x daily): approximately 12–18 months. Fish room with 5–8 tanks (2x daily): approximately 4–6 months. Large koi pond (10 Koi, feeding actively in warm months): approximately 6–8 weeks during peak feeding season. The 1KG format is most economical for fish rooms and ponds where volume consumption is high. For a single small community tank, the 500g Saver Pack at Rs 349 may be more appropriate to ensure the food is used within the 6-month post-opening freshness window.

Question 6

Is Fine or Medium better for adult Koi in a pond?

Accepted Answer

Medium Pellets (2.50mm) are the correct choice for adult Koi over 20cm body length. Adult Koi are large fish with broad mouths — they consume Fine pellets in large quantities without difficulty but the Medium pellet delivers more nutrition per bite, is more efficient in a pond environment where some food will always disperse before being consumed, and is the standard recommended pellet size for Koi in the 20–40cm size range. Very large Koi (40cm+) would benefit from even larger 4–6mm pellets that are more typical of dedicated Koi food formulations, but the Medium 2.50mm Optimum pellets are suitable for all but the very largest pond Koi.

Question 7

Can I mix Fine and Medium pellets in the same feeding session?

Accepted Answer

Yes — there is no issue with offering both Fine and Medium pellets during the same feeding session. In a tank with fish of different sizes, you can scatter Fine pellets for the smaller fish while dropping Medium pellets toward the larger fish separately. The different sinking and floating behaviour of the two sizes (both float but the larger Medium pellets are more visible and attract larger fish more readily) naturally distributes food between different fish size groups. This mixed approach is practical for community tanks that have both small tetras and medium-to-large cichlids in the same setup.

Question 8

Does the 1KG format have the same formulation as the smaller Optimum packs?

Accepted Answer

Yes — the Optimum Fish Feed 1KG Premium Growth Pellets contain the same formulation as the standard Optimum Fish Feed Growth Formula in the 100g, 200g and 500g packs: high fish-meal protein, natural carotenoid colour pigments and Vitamins C and E. The 1KG format simply provides this nutrition in a bulk quantity with the added benefit of pellet size choice (Fine 1.25mm or Medium 2.50mm) that is not available in the smaller packs. The Optimum 3-in-1 formula (sold separately) is a different, enhanced formulation with additional astaxanthin and beta-glucan immune support.
