Generally regarded as a hard to keep fish....I like to debunk most of those myths. They do take more care then your average tropical tank or goldfish, but they arn't THAT hard to keep. 1 Adult per 10gals, they can reach 6-7" sometimes 8" in diameter. They like to be in groups and I'd recommend a tank no less then 40-50gals to start with. Breeding pairs can be kept in tanks as small as 20gals.
They are gorgeous but after the catastrophy I had tonight......I posted what happened on the general discussion thread, I wont be buying anymore fish for a while. When Im feeling up to it again, I will get back toyou with any questions thanks for the info though its greatly appreciated.
