I had a plague hit my 20G last summer and lost everything but the crayfish which has grown up now a tough bastard! Out of work now and will build it up again, i put minnows in to detect problems i see now the crayfish is no good for that! The two minnows i had b4 died in it! Cause was the goldfish feeders! I know cause the two who survived being eaten was unaffected by whatever, and all others died. I thought at first the monnows but thought if it was they had it b4 and wouldn't die! If they had it they was a carrier, but carriers don't die! They have amunity!

Great collection of videos!
