Name: Scleropages jardinii
Origin: Asia to Northern Australia
My experience showed that S. jardinii grows up to 35 cm within a period of 7 months if being given enough food. I gave my pearl arowana feeder fishes, crickets, krills and also caterpillars. My pearly refused to eat dry or frozen food including frozen blood worms. He only takes live food probably because I have taught him to eat those live foods from the beginning. But at the stage of 35 cm, it is still hard for me to give him CENTIPEDE as his food. Once he tries to swallow and bite the centipede, it seems that the long body of such centipede makes it harsher for him to eat. So, I think it's better to give crickets at this early stage of 7 months.
The Pearl Arowana (Sceleropages jardinii) or Spotted Saratoga (also Saratoga jardinii) is commonly confused with a totally different species, the Barramundi (Lates calcarifer) which is not even of the same genus. These are impressive and striking fish who seemingly do not swim, but glide gracefully through the water. This fish is best suited to a species tank. Any fish that is small enough (even large fish) that can fit in its mouth will be devoured. New laws in Australia have greatly limited exports because of over harvesting in the wild, and all subspecies are prohibited from exports. These fish are well worth the effort and are a beautiful addition to any collection. A wonderful display of several individuals 1.2 meters and over are on permanent exibit in Underwater World, Maloolaba, Australia.
My pearl arowana has lived with me for about 1 and a half year. Now, she loves to eat frozen bloodworms. I've taught her to eat them by starving her for about a day or 2 maybe, in order for her to eat everything just to fill in her stomach. Then, now she can easily absorb all those nutrients in the frozen blood worm. Sometimes I buy crickets and mealworms. Once a week I will buy 3 or 4 small frogs for her. Frogs can make her color become brighter and her gills becomes shinier.
My pearl arowana is about half a meter long and four years old. Initially she ate dried arowana food pellets, then dried prawns, then fresh prawns, later small fish from the supermarket. Since I don't like feeding her live fish, I started feeding her live cockroaches. Now she won't eat anything other than cockroaches, and they are hard to come by!
I bought a pearl arowana about 8 cm long and first week I was feeding him guppies only. Next week I started feeding him small gold fishes. After one month I started feeding him small African catfish (mui) and cleaned sardine fish pieces with bones. It has been 6 months I am feeding him and it is 40 cm now. My pet shop owner said that African mui in their diet can make big difference in arowana´s growth. Sardine fish also very good food for them. I change water 15% twice weekly with possible substrate vacuuming. I never tried mouse or crickets or any other items to feed him, including pellets.
Many people say it is hard to get these fish to eat pellets. I have found it quiet easy. I just starved it for a few days. Plus having tankmates that will rush for the food will teach the fish to follow suit. Having tankmakes also keeps the fish calm as a solitary fish is much more likely to panic, jump and hit the lid hard. Insects are a great treat but pellets make life easier for the fishkeeper. I have not found the fish to be skittish at all. Keeping it with a large oscar, bala shark, silver dollar, pearl horseface.
