The mouth-breeding arowanas (silver arowana/Asian bonytongue), which grow up to approx. 120 cm long, originate from South America (Osteoglossum bicirrhosum) or from Southeast Asia (Scleropages formosus). They are exclusively predator feeders and also catch animals above the water surface. It is therefore important that the majority of their diet contains animal proteins. However, vegetable components are also important, as the animals eaten contain a lot of green food in their stomachs. This means their diet is based on a mixture of animal and vegetable proteins, as is the case with many predators which eat their prey in its entirety.
Colour formation in arowanas: Experienced breeders have been able to breed out very beautiful colours in the arowanas. The colours then need to be maintained with the right food, otherwise they will fade. Breeders report that even with their top breeding animals the colours only remain maximally developed with perfect nutrition. Carotenes in the feed naturally and especially enhance the red hues. There are the cheap, artificially produced carotenes that provide red fish flesh in commercial salmon farming, for example, and then there are the expensive, natural carotenes (astaxanthins) that come from shrimps. JBL uses only the high-quality astaxanthines. This is why many top breeders choose JBL food for their valuable breeding animals and offspring.
JBL PRONOVO food is prebiotic
Prebiotic food: Scientists are agreed that they promote digestion and thus health. In the case of our fish, there is another essential aspect: with better digestion, less is excreted and the water is thus less polluted, causing fewer algae problems and keeping the water cleaner. This aspect is significant, especially with strong feed converters like arowanas.
