Thats awesome. One of the coolest tanks I have still ever seen was at a great LFS in Virginia where we used to live. It was a 20g tall I think that had one yellow stripe marroon in it and rock all the way up the back wall. It had been going for about 3 years at that time and the one small BTA that was in there had turned into 7 huge ones and filled the tank in layers up the rock wall. The marroon just went bonkers spastically hosting all of them. Pretty cool
