Like all domestic discus it descends from wild fish of the Amazon basin and has been refined through decades of selective breeding in Asia. It suits committed keepers who can provide a warm, spotless, mature aquarium.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eAdult Size:\u003c\/em\u003e Around 15–18 cm (6–7 in) across\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLifespan:\u003c\/em\u003e 10 years or more\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eOrigin\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eNative to:\u003c\/em\u003e Captive bred; wild forms from the Amazon basin, Brazil, Peru, Colombia\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eHabitat:\u003c\/em\u003e Warm, still floodplain lakes and flooded forest among submerged branches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eFeeding\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eDiet:\u003c\/em\u003e Omnivorous, insect larvae and plankton in nature\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePreferred Foods:\u003c\/em\u003e Discus granules, beefheart mix, bloodworm, brine shrimp, blackworm, daphnia\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFeeding Habits:\u003c\/em\u003e Two or three small feeds daily; remove uneaten food promptly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eTank Mates\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBest with:\u003c\/em\u003e Own kind in groups of six, cardinal and rummynose tetras, corydoras, sterbai\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eAvoid:\u003c\/em\u003e Angelfish, barbs, plecos that rasp flanks, cool-water species\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eAggression \u0026amp; Behaviour\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eTemperament:\u003c\/em\u003e Calm and peaceful, but a cichlid\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eTerritoriality:\u003c\/em\u003e Pairs guard spawning sites; pecking order in groups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eExperience Level\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eDifficulty:\u003c\/em\u003e Intermediate to Advanced\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eChallenges:\u003c\/em\u003e Needs very warm, clean water and frequent large water changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eWater Parameters\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eWater Type:\u003c\/em\u003e Freshwater, soft and slightly acidic\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eTemperature:\u003c\/em\u003e 28–30°C (82–86°F)\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003epH:\u003c\/em\u003e 6.0–7.0\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eHardness:\u003c\/em\u003e 1–8 dGH\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFlow:\u003c\/em\u003e Slow to moderate; gentle\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eTank Size:\u003c\/em\u003e Minimum 300 litres for a group of six adults; taller tanks suit their shape\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eFinal Notes\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eKeep at least five or six together and remove any fish bullied off food. The blue deepens with age and shows best over a pale or bare bottom under moderate light; dark substrates wash it out. Weekly water changes of a third or more are non-negotiable. Sexes are near identical until a pair claims a vertical spawning site and both parents feed fry on skin mucus. A mature Blue Diamond is a stunning centrepiece.\u003c\/p\u003e","brand":"SimsTF","offers":[{"title":"5cm","offer_id":64680667382137,"sku":"STF-DISC-BLU-DIA-5cm","price":60.0,"currency_code":"GBP","in_stock":true},{"title":"9cm","offer_id":64680667414905,"sku":"STF-DISC-BLU-DIA-9cm","price":100.0,"currency_code":"GBP","in_stock":true},{"title":"13cm","offer_id":64680667447673,"sku":"STF-DISC-BLU-DIA-13cm","price":150.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1026\/3124\/4153\/files\/STF-DISC-BLU-DIA.png?v=1790096914","url":"https:\/\/birchwoodaquatics.myshopify.com\/products\/blue-diamond-discus","provider":"Birchwood Aquatic Centre","version":"1.0","type":"link"}
