Lyretail
A variant of Swordtail (Xiphophorus hellerii)
Representative Swordtailphoto — a dedicated image of this exact morph isn't available yet.
Both tail lobes extended into trailing points; males' modified gonopodium can impair breeding.
Keeper tips for this variant
Keep with gentle tankmates to protect the finnage; lyretail males may breed poorly, so keep standard-finned males if you want fry.
