Well my Cardinals were doing pretty well and reproducing until I rescaped the tank back in Oct. I added two large Seiryu stones and a moss wall. The moss wall didn't do well even though I tried several different varieties of moss. I think the higher temps that Cardinals like, 82-83, in this tank and the alkaline pH aren't the best for moss. It was however, great for some kind of dark green slimy looking growth that started on the moss wall and started spreading to the rocks. The shrimp wouldn't touch it. Over the course of the 4 months after rescaping my Cardinals were all but gone.
So I decided that the stones and moss wall weren't helping them and I rescaped again. This time I used the smaller Seiryu stones like I originally had and also made a little cave for them out of the rocks and added a couple pieces of Mopani wood to the tank. I also added an Anubias nana variegata and decided to only run the Vuppa when necessary (when I notice a film on the surface) as the shrimp seem to be more active when it's off and the water is calm.
I only had three adult Cardinals and two babies up until this week when I added 12 more that I got from Liam.
I just noticed today that I have one female with either very mature eggs under her tail or babies before their release. So I'm hopeful I can rebuild the colony.
I also noticed within the last couple of weeks that I have planaria. I didn't have them before the rescape so I'm guessing they came with some of the moss I bought. I'm going to try using one of the Gush Catch Pens tonight to see if I can get rid of them. I don't want to use any chemicals because I have a nice colony of Tylomelanias with several babies in with the Cardinals and White Orchids (Starry Nights). I'm not sure if planaria are actually harmful to the shrimp but if they attack the babies then they definately need to go. It's hard enough to keep these shrimp and they're expensive enough that I'm not going to allow some flatworms to harm them.
