[ 9 ] Like all Scleropages , Asian arowanas have long bodies; large, elongated pectoral fins , dorsal and anal fins located far back on the body; and a much larger caudal fin than that of their South ...
These fish are best kept with live or frozen feed and they easily outgrow the tank within eight to ten months. An aquarium with the minimum diameter of 6 by 3.5 feet (1.8 by 1.1 m) and 300 US gallons (1,100 L; 250 imp gal) is suggested as a bare minimum but 400–800 US gallons (1,500–3,000 L; 330–670 imp gal) is the best way to go.

Its maximum total length is typically considered to be 0.9 m (3.0 ft), [3] but there are reports of individuals up to 1.2 m (3.9 ft). [2] Unlike the black arowana , the silver arowana has the same coloring throughout its lifespan.
Heterotis niloticus - MHNT.

The world's smallest fish depends on the measurement used. [1]Based on minimum standard length at maturity the main contenders are Paedocypris progenetica where females can reach it at 7.9 mm (0.31 in), [2] [3] [4] the stout infantfish (Schindleria brevipinguis) where females reach it at 7 mm (0.28 in) and males at 6.5 mm (0.26 in), [1] and Photocorynus spiniceps where males can reach it at 6. ...
It commonly reaches fork lengths up to 80 cm (2 ft 7 in) and a mass of 8–10 kg (18–22 lb). Its maximum fork length is 108 cm (3 ft 7 in), and its maximum mass is 34.5 kg (76 lb). Determining the age of skipjack tuna is difficult, and estimates of its potential lifespan range between 8 and 12 years. [2] Skipjack tuna are batch spawners.
