Hi Alice. Sorry to hear about your fish. I was told this species of Corydoras was a hybrid. Got them from a local "Mom & Pop" fish store. I did a little research and from what I can tell, this type of Cory was possibly bred with Venezuelan Corys. Mine have a single orange strip right in the middle of the body on either side. Probably why they're call "Orange Saddle". I've never done anything special, except change half their water weekly. I understand that Corys can live for more than a 5 to 7 years. But, it's been my experience over the years that 99.9 percent of water keepers will make a mistake in tank management accidentally at some point and the fish die. I certainly know I've made my share.I had the same colony of corydoras for at least 12 years, probably longer. Lost a couple of the older bronze corydoras in about 2016 or 2017, bought a few at a fish store to raise the population, and despite quarantine the new ones carried something and I lost my colony. I don't put salt in my cory tanks. Period You talking about Orange Laser corydoras with the orange?
