I have hydrocotyle tripartita, and several different mosses. I'm not sure what you mean by small Java Fern. I have trident, needle, and normal. Had red, but I kind of lost it among the other java fern and I am not sure if I still have it. I do have small java plants, but don't have any of the mini varieties I've seen on TPT forum.
Down to 3 cardinals from 6. Mainly from my own tinkering and the heater sensor coming out of the water which raised the temp over 90. I have 7 or 8 goldens and 2 orange babies from the ones I bought from you. Ive got some yellows. Blue pearls. Tigers. Blue bees. And then some bkks coming.
Only thing I've added to my tanks is minerals to increase water hardness. Using old aquasoil, and lately while I have lots of berried shrimp haven't seen any baby shrimplets in a long time.
Shrimpnmoss is a local guy who seems to be the expert on shrimp. I believe he has some high end pure line Blacks. He advised me to increase water hardness. Saw a few baby golden bees yesterday. Hopefully this resolves my problems.
How are your cardinal shrimp doing? Something maybe for the future if and when I get enough tank space...
