When dismantling my 254L cichlid tank to move house I noticed the silicone coming away so transferred my 30+ fish to a spare 90 L tank-Aqua One 620. Within 24hrs all 4 of my silver dollars and a silver shark died at the same time and when I came home tonight I had lost an electric yellow and sulphur crest too. When I moved I had transferred the same water ( I never had problems ) and after the silver dollars died, did a 20 % water change and added additional filtration used in 254 L tank. The Aqua One 620 tank was previously set up for marine so am wondering if it has anything to do with that? By the looks of this electric yellow-hunched and losing colour I would say he is next to die. Any ideas? Sorry I have no freshwater tests-only marine. I use shell grit in my gravel to maintain PH and do regular water changes-not losing fish for over 12mths so don't do tests.
