Banded Chromide

The Banded Chromide, scientifically known as Etroplus suratensis, belongs to the Other family group. Adults reach a maximum size of approximately 30 cm and have a compressed body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a high level of biological waste.

To thrive, the Banded Chromide requires a brackish tolerant aquarium with a minimum volume of 450 litres and a tank length of at least 150 cm. Water temperature should be maintained between 24°C and 30°C, with a pH range of 7.5–8.5 and a general hardness of 10–25 dGH. A moderate water flow is preferred.

The Banded Chromide is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Standard / Adult and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

When setting up an aquarium for the Banded Chromide, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and smooth gravel or rounded substrate to protect their sensitive barbels. Keepers should note that expect substrate disturbance, so lightweight décor should be secured and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.

Classified as semi-aggressive, the Banded Chromide is a social species that requires the company of its own kind to thrive. When choosing tankmates, ornamental shrimp are not safe companions and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Banded Chromide is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide a keeper who can commit to a proper group of at least 4. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Banded Chromide like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is underestimating its social needs. A token pair or trio often behaves very differently from a real group.

The Banded Chromide will hunt and eat ornamental shrimp, making it unsuitable for shrimp-focused setups and will eat fry, so breeding efforts in the same tank are unlikely to succeed.
