Well yesterday I bought a pair of Ghost Glass Catfish, they only had two, I know I need more though. So Im a little frustrated to hear that they dont live long at all! Why do these creatures die off in a few months? Is it because they are kept in to small of groups maybe? Also Iv heard they were suppose to hit 5-6 inches then I heard no way theyll only hit 3 inches. Anyone have anything that ever reached over 3 inches?
