People will try to make money off anything.
All you need is a little sprig of java moss and it will grow in any tank. You will soon be throwing out the overgrown moss you will have in the tank. When that happens, give it away to a fellow aquarist. That's how I got mine. Someone gave me a handful.
Thank you for your reply.
I cannot understand why if Java Moss is so quick and easy to grow. It is expensive to buy. I already have Red Cherry & Blue Cherry Shrimps. I am soon going to get some Yellow ones.The Substrate I have is Black Sand and ADA Amazonia. I also placed small walnut size stones in one corner so that the shrimps can hide.
Hopefully you will get the new shrimps later this week, exciting stuff! They grow fairly quickly!
The babies will feed off the sponge so it doesn't surprise me to hear they like it there.
Pleased to hear it is going so well!
