My fish tank is ALIVE again!

Bought 8 little neon tetra yesterday and now my boring fish tank with 2 white cloud is beaming with life! Hopefully the new tetras live well in the new environment... oh.. and earlier, few months ago, one of the white clouds died so i have 2 white clouds now, 1 from the earlier batch and 1 from the later batch.. the remaining 1 from the later batch has been suffering from a disease that cause it to be hunchback.. on the good side, it has managed to survive so long without any problem so i decide not to isolate it... hopefully all the fishes live well together... :)
