It lived in water.
They are a tropical ray-finned fish.
The main difference between lobe-finned fish and ray-finned fish lies in their fin structure. Lobe-finned fish have fleshy, lobed fins supported by a bony structure, while ray-finned fish have fins supported by bony rays. Additionally, lobe-finned fish are believed to have given rise to tetrapods, including amphibians, reptiles, birds, and mammals.
Perch are lobe-finned. The fins on Perch fish are fairly rounded and distinct for this species of fish in the wild.

Ray-finned fish (Actinopterygii) are most closely related to other groups within the clade Osteichthyes, which includes lobe-finned fish (Sarcopterygii) such as coelacanths and lungfish. Among living organisms, the closest relatives of ray-finned fish are the lobe-finned fish, as they share a common ancestor that predates the divergence of these groups. Additionally, tetrapods, including amphibians, reptiles, birds, and mammals, are also closely related due to their descent from lobe-finned fish ancestors.
