Had a Black Ghost for about a year. Great fish. Feeding was problem for the Discus though, they are pigs. Went to a tackle store a got a box of red worms (there cheap a last for months in the frig). I would drop a few in the tank – the Black Ghost would chow down then go take a nap. I could feed the Discus and eat in peace. I lost him during a tank move and was going to get another – till I saw one in a LFS that was over 2 feet long!
