Hello and welcome fella glad you made it !
Common name Asian arowana/Dragon fish
Scientific name : Scleropages formosus
Synonyms: Asian Bonytongue
Size Up to 36" (90cm) reported, but usually smaller.
Origin Asia: Cambodia, Indonesia (Kalimantan and Sumatra), Malaysia, Thailand and Vietnam.
Tank setup A large tank with plenty of open swimming space.
Compatibility Keep with other very large fish which cannot be swallowed. Sometimes aggressive to other species, probably best kept alone as a specimen fish. Groups of similar sized individuals can be kept together, but this necessitates huge tanks which are beyond the means of most home aquarists.
Temperature 24-30oC (75-86oF)
Water chemistry Soft and acidic (pH 6.0-6.5) ideally, but the exact pH and hardness are not critical - the water quality is much more important (e.g. low nitrates, zero ammonia and nitrite).
Feeding Carnivorous: Live food including fish and insect larvae, will accept dead meaty foods, such as mussel and prawn.
Sexing : Very difficult. In mature fish, males may be slimmer and possess a larger mouth and discernable buccal cavity (to incubate eggs).
Breeding : A mouthbrooder, the eggs are carried in the mouth of the male. Has been bred commercially.
Comments : Silver, red and green forms of this fish exist. The red form is particularly prized. Many additional colour varieties have now been produced, and often attract a high price. This species is endangered in the wild, and is listed under CITES (Convention on International Trade in Endangered Species) Appendix I, meaning that international trade is tightly restricted. Captive-bred specimens are available to the aquarium trade and must be microchipped and sold with an accompanying certificate verifying their captive-bred origins. There are two other species in the genus: S. jardinii and S. leichardti.
