If you stocked no other fish with your FHM, they should be spawning soon and within a month or two you'll have so many FHM, you'll be amazed. You can assist them by putting in suitable spawning locations... Place, broken bricks, tiles, cinder blocks, stones, pieces of plywood, pallets,(anything semi flat that will lay near the bottom), in water 6"-18" in depth. The FHM like to spawn on the underside of this structure. I wouldn't bother stocking more FHM. If you stocked some back in Nov-Dec, they'll be spawning soon and you'll have 1000's.
The rosey red variation of the FHM is the exact same species except it's just a color morph. Because they are pinkish, they stand out and are usually the first to get eaten by predators. In ponds without predatory fish, I have seen them persist for a while, but ponds even with BG, they are usually gone in a year while their naturally colored buddies live longer.
Most people stocking FHM as the first fish in their pond. FHM are very hardy and can tolerate poor water conditions. They also make a great starter feed for young bass, getting them off to a great start before they get larger and begin to feed more readily on sunfish.
