Fish Crazy
My firts lot of corys were 3 Bronze ones, nowever they must have been a bad lot as 2 died with in 3 days of getting them home. So i added another from a different fish shop it was marble cory. They both seemed to get on well and have done for the past 6 months, but to my surprise the marble was dead this morning, it was fine last night on doing a water change! Any ideas whats happened?
