Short bodied fish commonly occur in normal spawns. It’s a spinal deformity. Short bodied fish don’t always mean they are hybrids. It seems like the trendy thing to do now is call anything short-bodied a parrot hybrid, since that body shape is now easily identifiable to most hobbyists as a blood parrot. I am seeing lots of stores doing that with convicts now as a way to market deformed fish to the unsuspecting hobbyist.
Either way it is not a normal Herichthys and I wouldn’t use it for breeding at all if you do own it.
