About 3 weeks ago I came out in the morning to find my cichlid tank had turned belly up and all my fish were floating on the top dead.
Being in the middle of selling my house I decided not to do anything with the tank, cleaned out the dead fish, and just switched everything off, filter, heater, airline etc.
Today I finally got around to emptying the tank and was gaily syphoning the water out when to my surprise I saw a giant Danio swimming around. As the water got lower I found 1 adult electric Yellow, 2 young juveniles and 2 giant Danios.
It amazes me that the fish could have survived this length of time with no heating and without any food for the time.
They are now comfortably swimming in a new tank with other cichlids.
