The Pearl Eartheater, Geophagus brasiliensis, is the substantial South American cichlid sold in the trade as Brazilian High-Hat, and in the older Petra wording for this SKU as “Brasilian High-Hat”. It is not a small community fish. It is a confident, bottom-working cichlid with a broad head, blue-green pearling, yellow-gold highlights and a habit of sifting through the substrate while it searches for food.
This listing covers the 0405 parent product and its size variants: 4-5 cm, 5-6 cm, 7-9 cm and XL. Those sizes are juvenile to part-grown sale sizes, not adult size. A well-kept G. brasiliensis can reach around 28 cm, so plan the adult aquarium first and then choose the size that fits your stocking plan.
The substrate is the heart of the setup. This fish spends much of its time near the bottom, investigating sand and fine gravel, so give it a smooth, clean substrate that will not damage the mouth or gill covers. A bare, sharp or dirty floor turns a natural behaviour into a stress point; a soft sand area lets the fish feed and display properly.
Use a spacious aquarium with open swimming room, sturdy wood or stonework and clear territorial boundaries. Plants can work if they are robust, protected or attached to hardscape, but delicate stems may be disturbed by digging. Filtration should be strong enough for a large cichlid that eats well and produces real waste, while flow should still leave calmer patches near the bottom.
The species is adaptable for a South American cichlid, which is useful for UK keepers with established heated aquariums. Keep the water clean and stable rather than chasing extremes. Regular water changes matter more than trying to hold a single exact number inside the range.
Pearl Eartheaters do best on a varied omnivorous diet. Use quality sinking cichlid pellets or granules as the base, then rotate in frozen or live foods such as bloodworm, brine shrimp, mysis and chopped seafood where appropriate. Add some vegetable matter through spirulina, algae-based foods or blanched greens. The goal is not just colour, but steady growth without a heavy, fatty diet.
Feed in a way that suits a bottom forager. Smaller portions that reach the lower half of the tank are usually more useful than one large surface feed that faster midwater fish steal before the eartheater gets involved.
This is a robust cichlid for a robust community, not a peaceful nano-fish companion. Suitable tankmates include similarly sized South American cichlids with enough space, larger peaceful catfish such as many plecos, and sturdy midwater fish that are too large to be treated as food. Avoid tiny tetras, shrimp, timid species, slow long-finned fish and very aggressive cichlids that would turn every boundary into a fight.
Adults can become territorial, especially as pairs mature. If you keep more than one cichlid, build the layout with sight breaks and more than one defensible area. A single specimen can be a strong centrepiece; a pair or group needs more room and more careful observation.
All four variants were out of stock at the time of this review, so this page is written as care guidance and size-planning rather than a hard availability promise. When a size is available again, choose with the adult 28 cm fish in mind. A juvenile may look manageable in a shop bag, but the adult needs a serious aquarium and tankmates chosen around its final size.
After arrival, keep the lights low, avoid immediate chasing or netting, and offer food only once the fish is settled. Watch the first week for heavy breathing, hiding, bullying or refusal to feed. In a clean, roomy aquarium with suitable companions, this species becomes an active, visible cichlid with much more character than a generic “large fish” listing suggests.
