Thanks for the link Ch4rlie, yes they are red cherries. The tank is heavily planted, fish include Cardinals and a pair of Rams. I also have a smaller tank also well planted which I use for fry. I am thinking of putting the shrimp in there for a while and introduce them into the main tank a couple at a time to see how they get on. I may wait till they have some shrimplets first. Comments on this idea please.
