A quick update, of a good news/bad new variety.
First up, some good news, the shrimp in my bee tank are doing quite well. They're excellent feeders (don't put your fingers in my wife reckons they'll remove them... lol) and the tank is pretty much spotless with just a tiny patch of algae on a filter sponge. Little sods have uprooted quite a lot of the dwarf hairgrass though... I lost a single black in this one, oddly enough right after feeding them snowflake...... I want to see berried shrimp and babies in there though before I consider adding a few true Taiwan bees.
Which bring me to my blues tank... Had a LOT of deaths once again in this one, right up until the point where I STOPPED feeding the unbranded snowflake I'd been sent in a "goody box" deal. Since I stopped feeding this, and switched to ONLY feeding my branded foods (Dennerle, JBL and GlasGarten) touch wood I haven't lost a single shrimp in there. I have a single berried female in there too, so I have high hopes this will help to rebuilt my colony again. This has led me to the conclusion though that the food was tainted with some form of toxic substance, not least as I watched some of the shrimp die, they acted EXACTLY like some shrimp I had years ago that got exposed to fly killer spray (my wife had used it in the kitchen without telling me, my acclimatisation bowl happened to be in there at the time, the rest is history with only some of them been saved when I realised what must have happened and quickly moved the surviving shrimp into their new home), sinking down onto their sides and twitching repeatedly, slowing down until death. Needless to say that snowflake has gone in the bin....
Kinda good news though in that a KNOWN cause is far better than an unknown one, not least as it means that in time I can restock in there happily without worry.
