Buy a group of six to let a pair form; sexing is difficult, with males showing a small nuchal hump near spawning. Breeding is rare in captivity and parents often eat their eggs. Dim light, branches and leaf litter make them thrive.\u003c\/p\u003e","brand":"SimsTF","offers":[{"title":"Altum 5cm Wild Caught","offer_id":64680659091833,"sku":"STF-ALTUM-ANGEL-altum-5cm-wild-caugh","price":100.0,"currency_code":"GBP","in_stock":true},{"title":"F1 Altum 5cm","offer_id":64680659124601,"sku":"STF-ALTUM-ANGEL-f1-altum-5cm","price":50.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1026\/3124\/4153\/files\/STF-ALTUM-ANGEL.png?v=1790096787","url":"https:\/\/birchwoodaquatics.myshopify.com\/products\/altum-angelfish-orinoco-pterophyllum-altum-5cm","provider":"Birchwood Aquatic Centre","version":"1.0","type":"link"}
