Week one has passed and I have seen 5 of the 15 shrimps today, so I am very happy about that, they could have all survived but I will never know that as the tank is so dense with plants/wood etc (lesson for next time - less is more) and there are likely some hiding, but at least whatever the early problem was seems to have vanished/cleared as the shrimp previously put into the tank vanished by the next day of being added, and that was before I got the fish. I probably won't replace the fish though when they die if the shrimps carry on working as I am sure they would pick off any newborns if they see them.
Whether I have the will power to hold off buying another load (the person I got them from have all the others I would like to get) remains to be seen? I should give it a bit longer, and it has turned quite wintery here all of a sudden! There is a quite small//bright red cherry (very pretty with the stripe) in that tank that has been there a while, so red taiwan bee may be safe with the fish as well???
