How to Breed Clownfish at Home: A Brisbane Hobbyist's Guide
Posted by Gallery Aquatica on
Clownfish are one of the few marine fish that will spawn readily in a home aquarium, which is exactly why so many people try breeding them and exactly why so many give up after the eggs hatch. Getting adults to spawn is the easy part. Keeping the larvae alive for the first ten days is where most first attempts fall apart, usually because there was nothing small enough for the babies to eat sitting ready on day zero.
This guide walks through the process in litres and Celsius, the way it actually plays out in a Brisbane lounge room, not a Florida fish farm.
What you need
- A bonded pair, ideally tank raised ocellaris or percula, not two random juveniles thrown together
- A dedicated breeding tank, 90 to 150 litres is plenty for a pair
- A terracotta pot half or a flat tile as a spawning site
- Heavy protein feeding, we recommend Vitalis Marine Pellets as a conditioning staple
- Live rotifers and phytoplankton cultured and thriving before the eggs hatch, not ordered the day after
- Stable salinity, temperature around 26 to 27 degrees Celsius, and a slightly extended photoperiod
Step by step
1. Pair them up and give it time
Two juveniles will often pair naturally, with one becoming dominant and eventually turning female. This can take months. Do not rush it by adding a bigger fish to force the issue, that usually ends in one dead clownfish.
2. Condition heavily
A pair getting ready to spawn eats like it means it. Feed a varied diet several times a day, rotating pellets with frozen mysis and enriched brine. Vitalis pellets are a good base because the fat and pigment content supports egg quality, not just growth.
3. Give them a site and stable water
Place a terracotta pot or tile in a sheltered corner. Clownfish are fussy about cleanliness near the nest, so keep nitrate and phosphate low with regular water changes. Stable parameters matter more than any single number.
4. Watch for the spawn
A ready pair will clean the spawning site obsessively for days before laying. The clutch itself is a dense orange to reddish patch of eggs, guarded fiercely, usually laid in the evening. Eggs hatch roughly 7 to 10 days later, timed to a dark night, which is why clownfish breeders often dim lights on hatch night rather than leave them bright.
5. Have the larval food ready before hatch night
This is the step people skip and it is the one that decides everything. Clownfish larvae need food within hours of hatching or they starve. You need live rotifers already cultured and dense in a separate larval tank, green water from live phytoplankton to keep the rotifers fed and the water quality stable, and dim lighting to help the larvae find food. Set this up a full week before the expected hatch, not the morning after.
6. Move or siphon the larvae
Many breeders gently siphon larvae into a bare bottom rearing tank on hatch night, since parents will often eat their own fry once the light triggers a feeding response. A simple 20 to 40 litre bare tank with an air stone and green water works better than anything complicated.
An optional finishing touch
Once your fry settle and colour up, some breeders like to give them a host anemone down the track. An aquacultured bubble tip anemone, when one is in the live stock range, is a reasonable, reef safe option that lets juveniles express natural hosting behaviour, though it is entirely optional and not needed for the fish to thrive.
Gallery Aquatica often has clownfish in stock at the Brisbane shop. Unlike a lot of other retailers, we deliberately do not post or air freight live fish anywhere in Australia. That means clown fish are in-store pickup only, so if you want to buy clown fish, come in and have a look at what is swimming that week. It is a welfare choice, not a workaround, live animals travel best when they do not travel at all. Dry goods, food and equipment still ship normally with free shipping over $150.
Where most breeders actually fail
| Stage | Common mistake |
|---|---|
| Conditioning | Underfeeding, or feeding only flake |
| Spawning | Disturbing the pair or the pot too often |
| Hatch night | No live rotifers or greenwater ready |
| Days 1 to 10 | Water quality crashing in the tiny larval tank |
