No mud minnows out here that I know of. I did drop in 40 FHM today, no photos but let them equalize and away they went. Big pond filling amazingly fast. 6 feet in last two weeks. I made an isolated pond for an eventually bg kiddie pond, but stocked fhm in there also. Just made a mini dam and a diversion channel. Interesting on the backhoe cut two feet wide and about 4 feet deep, exposed a few aquifers. I'll probably go with 40-50 a week, then drop in pallet perf pipe rig.
