Hi,
I have a nano tank, 26 litres or so, about 6 months old. It is heavily planted with FE CO2 and TPN+ (1.5ml per day) added. I bought some cherry red shrimp a few months back, 8 of them, and one by one they have slowly died off. I cant put my finger on the problem. I do weekly 40% water changed and the temp is around 23-25 degrees. My ammonia and nitrites are 0 and i keep 2 otto's and 5 endlers in there. I have had one endler and 1 otto die on me too in this time. I think the otto waqs probably not too healthy to begin with as it didnt eat from day one and the endler was a mystery to me, the others seem fine.
I had noticed yesterday what looked like a split i a shrimps shell between its head piece and body. I took this to be the start of a moult, but it died just now, i found it upside down on the bottom, it was struggling to right itself so i tipped it up the right way, but it died shortly after. Strangely part of its tail and part of its under body has gone a dark colour.
I know the problem with copper and shrimp, i havent added any medicines, but our hot water tank is a copper thing, i added watewr from the hot tap for a water change when i first had the tank, would this be the cause? I use dechlorinator every water change.
I have 2 shrimp left, they are quite small and havent grown too much since ive had them. I wont get any more, but as cherries are the hardiest of shrimps i cant understand what is wrong.
Cheers
Peter
