Pond Boss Forums STOCKING A NEW POND Types of fish to choose What should I stock first?

After 3 weeks, you may have some GSH that have increased up to 1/4 or 1/2 inch. If I had to guess though I would say the bigger ones would be your FH. If your FH had spawned, their fry would be smaller than your GSH regardless. If you did have some other species in there, that is another possibility. Post your picks when you can and you should get a more definitive answer.
