Oscar

Astronotus ocellatus

一半是鱼，一半像小狗：虎鱼会认脸、自己重布景，而且总会长到超出您以为足够大的鱼缸。

Care tips

• Plan for 285 L+ per adult; they reach 30 cm or more
• Keep 23-27 °C with heavy, oversized filtration
• Change 40-50% of the water weekly; the bioload is huge
• Feed quality cichlid pellets with occasional whole foods
• Secure the lid and anchor decor — oscars redecorate
