3. Symptoms / Problem description All the young L201's started dying after feeding Cos lettuce. I have been using Cos lettuce to raise all my L333's & 201 since 2013 never had an issue. This time I have lost a whole tank of 40 young I breed all 2.5 - 3cm. Noticed a couple dead didn't think too much changed some water. Next day a lot dead and can see in there guts dark green suspecting the cos lettuce has been treated prior to market? Or chemical reaction in packaging? Also seen they had a white external bacterial on them. I had already used 1 out of the packet of 5 the week before they were all fine. Feed to all my other tanks also but were adult colonies of L333, 134, 201 & 10a no issues with adults just the young.
