Mature males develop the classic bicolour pattern, usually with a blue, grey-blue or purplish front half and a yellow, orange or orange-red rear half. Females are typically slimmer and less intensely coloured, but they are important for natural group behaviour and male display.\u003c\/p\u003e\n\u003cp data-start=\"2600\" data-end=\"2879\"\u003eAdults usually reach around \u003cstrong data-start=\"2628\" data-end=\"2640\"\u003e10–12 cm\u003c\/strong\u003e, with males becoming noticeably deeper-bodied as they mature.

It needs open swimming room through the middle and upper levels, with plants, wood or décor around the sides and back for security. Boeseman’s Rainbowfish are peaceful, but they are fast and energetic, so they are not ideal for tiny tanks, shy nano fish or slow delicate species that may be unsettled at feeding time.\u003c\/p\u003e\n\u003ch2 data-section-id=\"1jzuw08\" data-start=\"3345\" data-end=\"3374\"\u003eRecommended Aquarium Size:\u003c\/h2\u003e\n\u003cp data-start=\"3375\" data-end=\"3791\"\u003eA practical minimum is \u003cstrong data-start=\"3398\" data-end=\"3424\"\u003e240 litres for a group\u003c\/strong\u003e, with a tank length of at least \u003cstrong data-start=\"3457\" data-end=\"3467\"\u003e120 cm\u003c\/strong\u003e recommended. Larger aquariums are preferred for adult males, stronger display behaviour and mixed rainbowfish communities.

Offer quality flakes, small floating or slow-sinking granules and rainbowfish pellets as the staple diet. Supplement with frozen or live foods such as daphnia, brineshrimp, cyclops, mosquito larvae and bloodworm. Include vegetable or algae-based foods for balance. Feed measured portions, as rainbowfish are enthusiastic feeders and can outcompete quieter fish.\u003c\/p\u003e\n\u003ch2 data-section-id=\"2vr35r\" data-start=\"5359\" data-end=\"5388\"\u003eBehaviour in the Aquarium:\u003c\/h2\u003e\n\u003cp data-start=\"5389\" data-end=\"5768\"\u003eThis species spends much of its time in the middle and upper levels, moving in a loose group. Males display with raised fins, stronger colour and quick side-by-side movements, especially in the morning or after water changes. They are lively rather than aggressive, and a well-sized group usually shows better colour, confidence and natural behaviour than a small number of fish.\u003c\/p\u003e\n\u003ch2 data-section-id=\"gyou4p\" data-start=\"5770\" data-end=\"5784\"\u003eCare Notes:\u003c\/h2\u003e\n\u003cp data-start=\"5785\" data-end=\"6231\"\u003eBuy small specimens with their adult size in mind. They need a long tank, a group, stable mineral-rich water and good filtration. Do not keep singly or in pairs, as small numbers can become nervous and less colourful.
