I have stocked many a pounds of GSH minnows from the wholesale bait store about 30 mins from my moms pond. Normally 10% are dead by the time I get them home, and 50% or so dumb they end up swimming up on the banks. At my new house I drained the top smaller pond and found I have GSH, they have lived in muck 2inches of water and I have kept about 10 lbs alive in 35 gallon rubber maid containers for 4 days now without one mort .... I just do 50% water changes each day. No acclimating cold water right in. Is this normal in native GSH vs bait shop GSH ?
