Similar to Black Moors

Fantails go dormant but are targets for predators and tankmates while sluggish. Slightly hardier than moors but still at risk. Author kept some 5 years outdoors but lost them to predators, not cold.

Indoor wintering preferred. Author now keeps fantails in 65-gal indoor tank for safety.
