Yellow Jacket Cichlid Parachromis friedrichsthalii
The Yellow Jacket Cichlid is a golden, black-blotched predator with attitude to match, one of the larger and more challenging Central American cichlids in the hobby. Reaching up to 30cm, it is a hardy, aggressive ambush hunter best suited to a dedicated large-species tank or a rough-and-tumble grow-out setup rather than a general community.
Natural Habitat
Parachromis friedrichsthalii is native to the Atlantic-slope rivers, lakes and lagoons of Central America, from Belize and Guatemala down through Honduras and Nicaragua. It favours warm, sluggish or still waters with cover from submerged wood, rock and vegetation, from which it ambushes prey – even feigning death to lure smaller fish within striking range.
Appearance
A large, elongated predatory cichlid with a golden-yellow body scattered with dark blotches along the flanks and a prominent dark eye-stripe. Adult males grow noticeably larger than females and develop a more pronounced nuchal profile and stronger colour when in breeding condition.
Temperament and Compatibility
Aggressive and territorial, with a genuine predatory streak – this is a fish that sees anything smaller than itself as a potential meal. It is best kept singly or as a well-matched pair in a large species or large-cichlid tank, not in a general community. Even paired adults can turn on each other if the tank is too small or lacks broken sightlines.
Feeding
A carnivore with a big appetite. Offer a quality large-cichlid pellet or stick as the staple, supplemented with prawn, whitebait, earthworms and other meaty foods. Feed in modest portions two to three times daily rather than one large meal, and expect a hearty bioload requiring strong filtration.
Care Requirements
This is a big, messy, predatory fish and not one for beginners or small tanks. Provide a minimum of 400 litres for a single adult, 600 litres or more for a pair or larger setup, with powerful filtration and regular substantial water changes. Furnish with sturdy rockwork, caves and driftwood for territory, leaving open water for swimming, and use a secure lid as large cichlids can be surprisingly good jumpers.
Breeding
An open substrate-spawning cichlid that forms strong, aggressive pairs. Both parents guard the eggs and fry fiercely once spawning begins, and tankmates (including each other, if not well matched) can be at real risk during this period. A very large, well-structured tank is essential for safe breeding.

Is your tank ready?
Is your tank ready?
A few quick checks before you buy save most of the common losses.
Tank size for the adult, not the juvenile
Check the species page for max size and minimum tank size, and size your tank for what this animal will grow into – not what it looks like today.
Cycle first
Your tank needs an established nitrogen cycle before livestock goes in. Adding fish to an uncycled tank is one of the most common causes of early losses.
Match the conditions
Check temperature and pH on the species page against what your tank currently runs, and make sure you've got the right gear – a heater for tropical species, adequate filtration turnover, lighting and CO2 for planted tanks, or the right salinity setup for marine.
Start conservative
New to the hobby? Start with a small number of hardy species and add slowly – overstocking a new tank is one of the fastest ways to crash your water quality.

Packed Safe
Live Fish
- Oxygen-filled bags – each fish is bagged in clean water from its own system with a generous charge of pure oxygen, giving many hours of safe transit time.
- Double or triple bagging – spiny or sharp-finned species (catfish, plecos, marine oddballs) are multi-bagged with liners so a spine can't cause a leak.
- Dark, calm transit – bags are packed upright in the dark, which keeps fish calm and lowers their oxygen use during the trip.
Live Corals & Inverts
- Individually bagged or cupped – each coral travels in its own bag or rigid cup of system water, sized so the piece can't knock against the sides.
- Frags secured – frag plugs are held so they can't tumble or land face-down against the polyps.
- Inverts packed to species – shrimp, snails, starfish and anemones each get the packing method that suits them, not a one-size-fits-all bag.
Live Plants & Tissue Cultures
- Moist, not swimming – plants travel wrapped in damp paper inside sealed bags, which prevents both drying out and rot in transit.
- Tissue culture cups sealed – cultures stay in their sterile cups, cushioned so lids can't pop.
The Box
- Insulated foam boxes – all livestock ships in polystyrene-lined cartons to hold temperature steady.
- Heat or cool packs by season – we add heat packs in winter and cool packs in summer heat waves, based on the forecast for your delivery route.
- Void fill and bracing – bags are braced so nothing shifts, even if the box travels on its side.
When Your Box Arrives
Open the box promptly, check everyone in, and follow our Acclimation Guide before releasing anything into your tank. If something has gone wrong in transit, take photos of the unopened bags straight away and see our Live Fish Arrival Guarantee for what to do next.

Quarantine
Why quarantine
Quarantining new arrivals before they go into your main tank protects the fish you already have from disease, and gives new stock time to settle and start feeding under close observation.
Freshwater Fish
- Duration: 2 to 4 weeks in a bare-bottom tank with a cycled sponge filter.
- Watch for: white spots, flicking or scratching, laboured breathing, clamped fins, and loss of appetite, checked twice daily.
- Medication: only if a problem appears – quarantine is for observation, not routine treatment.
Marine Fish
- Duration: around 4 weeks minimum.
- Options: observation only, a copper treatment held at 2.0 to 2.5 ppm for at least 30 days, or the Tank Transfer Method (four transfers over about 12 days).
- Flukes and worms: treated with praziquantel, with a repeat dose about a week after the first.
Full details: see our Fish Quarantine Guide, and our Freshwater Fish Quarantining at Home and Marine Fish Quarantining at Home guides, for tank setup, dosing, and day-by-day steps.
Acclimation
Before you start
Test your aquarium water, gather a clean bucket and net, and dim the room lights. Never pour transport bag water into your aquarium – always net your livestock out and discard the bag water, since acclimating too quickly after CO2 build-up in the bag can make trapped ammonia rapidly more toxic.
Freshwater Fish
Float the sealed bag for about 15 minutes to match temperature, then open it into a bucket and add roughly a cup of aquarium water every 5 minutes for about 45 minutes. Net the fish into the tank, keep the lights off for the rest of the day, and hold off feeding until the next day.
Marine Fish
Use the same cup method as freshwater fish, but keep the lights off or dimmed for at least 12 hours after introduction, and hold off feeding until the next day. We recommend quarantining marine fish before adding them to your display.
Corals, Clams & Invertebrates
- Drip acclimation is recommended: 1 to 2 drops per second until the bucket volume has at least doubled, around 45 minutes for fish-safe inverts and 60 to 90 minutes for corals and clams. Echinoderms such as starfish, urchins and sea cucumbers need the slowest acclimation of all.
- Handle corals and clams by their base, skeleton or frag plug only – never the soft tissue, polyps or mantle.
- Light acclimation: place new corals low in the tank away from strong light and flow for the first few days, then raise them gradually over 1 to 2 weeks.
Full details: see our Acclimation Guide for the complete drip and cup methods and coral dipping.
