§1What this business is
This is fish farming for the aquarium trade, not for the table. Brood fish are kept in cement tanks and glass aquaria under a shed; the young are reared for a few months and sold by the piece. Beginners start with livebearers (guppy, molly, swordtail, platy), which mature in 4–6 months and breed easily; egg-layers need more skill. Fish are fed farm-made feed and live food such as Daphnia and Tubifex worms. The profile costs one unit of about 25 sq m with 1,000-litre cement tanks, a pump, an air blower and a few small aquaria, for three kinds of fish — hard-water, intermediate and soft-water. Sales go to hobby centres (aquarium shops), agents and exporters, or directly to hobbyists.
Capacity: Fish numbers are not printed for the 25 sq m unit. Yearly income per unit in the profile: ₹44,000 (hard-water fish), ₹48,400 (intermediate) and ₹82,500 (soft-water fish).
§2Is it right for you?
Who it is for
A patient beginner, women's group or fish farmer with clean water, a small shed and an aquarium market within reach.
Who it is not for
Anyone who cannot check the tanks every day or has no steady supply of good water.
Advantages
- Starts small — one unit costs under ₹1 lakh
- Needs only about 25 sq m, so it can run in a backyard
- Livebearers such as guppy and molly breed easily, several times a year
- Fish are sold by the piece to shops, agents and exporters
Drawbacks
- Profit from a single unit is small — ₹6,500 to ₹19,000 a year in the profile
- Breeding slows down in winter
- Egg-laying and soft-water fish need much more skill
- Live fish must be packed and moved quickly to the buyer
Skills you need
- Telling male and female brood fish apart and pairing them
- Keeping water clean, aerated and at the right hardness
- Raising live feed such as Daphnia and feeding without overfeeding
- Spotting and treating fish diseases early
Why difficulty 2/5: Low cost and simple tanks, but live fish need daily care and clean water.

- Agents and ornamental fish exporters

Good to know
- The profile lists the ten most traded groups as tetra, guppy, goldfish, catfish, molly, gourami, platy, loach, cichlid and barb.
- Backyard model in the profile: five 3 ft × 2 ft × 2 ft tanks and a year's inputs for about ₹6,600; 3,500 fish sold at ₹4 each bring ₹14,000 in two cycles.
- The profile also lists a larger farm (4,000 sq ft shed, 114 concrete tanks, pump and aeration) whose fixed items add up to ₹10 lakh, but its expenditure total for that model does not add up, so treat those figures as indicative only.

§8Export potential
Confirm the HS code in the DGFT ITC(HS) lookup before you export
Export council / board: MPEDA (Marine Products Export Development Authority)
- The profile counts 86 major breeding units and 35 major ornamental fish exporters in India.
- Exporters buy from breeders, so a small unit usually reaches export markets through an agent or exporter.
§9Risks — where people fail
- Disease or bad water can kill a whole batch
- Overfeeding spoils the water quickly
- Predators and power cuts that stop aeration
- Depending on one trader for sales and price
