Apparently I started to put shrimps into my new tank, i'm using the shrimps to start the tank, I have 20 crs and 2 blue shadow King Kong.
I was going to keep it empty for another month, but couldn't resist the crs, the shop was selling them for little over GBP 1 for one or GBP 10 for 20, the quality was excellent, and it seem like a cross between crs and red wine, the king kong was GBP 2.50.
Forgot to mention, you catch your own shrimps.
Update on my previous shrimps, the babies shrimps has all turned from brown to black, the rest of the shrimps are all doing alright.
