Pond Boss Forums STOCKING A NEW POND Raising Forage and Bait Shiners in 55 gal aquarium ?

I tried to raise 18 4" golden shiners TWICE in my big aquarium stocked with 7 3-6" CNBG and 24 2-3" FH in it. Both times, all seemed to be going well for about a month after adding. Then BAM! ALL 18 died within 3 days of each other. No other fish showed any sign of stress with no changes in good water conditions. Never did figure out what went wrong.
