Peacock Bass Care Guide: Cichla Species Predator Tank Setup

Peacock bass are the showpiece predators of South American rivers and one of the most popular monster-fish choices in Singapore. This peacock bass care guide covers species selection, tank sizing, filtration, and the feeding regime needed to keep Cichla in long-term health. At Gensou Aquascaping in Everton Park we have commissioned many custom builds for peacock bass keepers, and the single biggest lesson is that these fish outgrow starter tanks alarmingly fast. Plan for the adult size from day one or the fish ends up rehomed within eighteen months.

Species Overview

The genus Cichla contains around fifteen described species, with Cichla ocellaris, Cichla monoculus, and Cichla temensis being the most common in Singapore. C. temensis, the speckled peacock, is the giant of the group, reaching 70 to 80 cm in home aquariums and over a metre in the wild. C. monoculus stays smaller at around 45 to 55 cm and is the pragmatic choice for most home tanks. Juveniles of all species look similar, so buy from a trusted importer who can confirm the origin.

Tank Size and Build

For C. monoculus the minimum long-term tank is 240 cm long, 75 cm wide, and 75 cm tall, holding roughly 1,350 litres. C. temensis needs 300 cm or more of length. These dimensions assume one fish. Groups require proportionally more footprint as territorial fights cause serious injuries. A second fish is only realistic in tanks over 2,500 litres.

Singapore HDB flats present a floor-loading problem at these volumes. BTO blocks tolerate around 150 kg per square metre. A 1,500 litre tank with stand and water exceeds that on a single square metre, so spread the footprint across a long stand or consult HDB and a structural engineer before commissioning. Landed and condo owners have more latitude but should still verify with the developer.

Filtration Scale

Peacock bass are voracious feeders and produce enormous waste. Filtration capacity should target four to six times turnover per hour through a sump the size of a small bathtub. A 500 litre sump with compartmented bio-media, a large mechanical sock, and a protein skimmer rated for brackish use handles the load. Powerheads in the display give the fish current to swim against, which keeps muscle tone and feeds natural behaviour.

Plan water changes at 30 to 50 per cent weekly. At 1,500 litres that is 450 to 750 litres of PUB water per week, which means a dedicated RODI line or pre-treatment barrel becomes essential.

Water Parameters

Peacock bass tolerate pH 6.0 to 7.5 and GH up to 15, but prefer slightly acidic soft water. Singapore tap water is ideal once dechlorinated. Temperature 26 to 30 degrees Celsius matches ambient conditions and rarely requires a heater. Ammonia and nitrite must stay at zero, and nitrate under 30 ppm. Stable parameters matter more than perfect ones, as these fish handle gradual drift poorly.

Feeding Regime

Feed juveniles small fresh prawn, chopped tilapia fillet, and occasional live guppies two or three times daily. Adults eat large pieces once a day or every other day. Avoid feeder goldfish long-term, as thiaminase and fatty tissue cause liver disease. A balanced diet includes prawn, squid, mussel meat, and occasional pellets such as Hikari Massivore or Okiko Gold.

Singapore wet markets sell affordable whole prawn and squid at 15 to 20 SGD per kg, which lasts weeks when frozen in daily portions. Bulk feeding from human-grade seafood is both cleaner and cheaper than dedicated fish-store feeder food.

Tankmates

Peacock bass dominate any community they are added to. Pair them only with robust species of similar size or larger, such as silver dollars, large plecos, or other peaceful cichlids at adult size. Never mix with smaller fish, which vanish overnight. Catfish such as Pseudoplatystoma tiger shovelnose make interesting tankmates but require even larger tanks.

Singapore Availability

Peacock bass are carried by Qian Hu, Polyart, and specialist shops along Pasir Ris Farmway. Juvenile C. monoculus runs 25 to 60 SGD, C. temensis 120 to 250 SGD, and rarer species such as C. intermedia up to 400 SGD. Buy at 8 to 15 cm for the healthiest starting size. Look for colour, active swimming, and intact fins.

Conclusion

A peacock bass is a ten-year commitment that demands space, filtration, and steady feeding. Size the tank for the adult, feed fresh seafood, and verify floor loading before installing. For custom tank fabrication and monster-fish consultations in Singapore, the team at Gensou Aquascaping at 5 Everton Park is happy to help plan the build.
