Oh, and because no one has stressed this yet (as far as I've read) that 10 gallon tank is *really* not the best because in addition to the goldfish alone needing a bigger tank to be happy, your glow light tetras are *much* happier if there are at least 6 in the tank, which would overcrowd that tank even more. You can sometimes get away with an overstocked tank, but that will require much more dedication to maintaining it.Thank you everyone for responding and being so kind Moonstruck and Homedog. I'm trying the best that I can to keep these guys healthy, yes the glow tetra fish and the platy and goldfish are all 3 years old. I will research the re-cycling of the tank and learn how to keep the water parameters under control. Thanks so much. When I used to clean the tank, and strip it down, the fish would be placed in a fish bowl, individually. Only for about 20 minutes, then they would be added back into the tank. Maybe not a brilliant idea, but I wanted to try to clean the tank and take the bad bacteria out, even though I didn't know that I was messing with the good bacteria.
Have you gotten any actual param readings yet?
See what I get for trying to help? Education! :thumbsup:Goldfish live VERY long lives compared to other ornamental fish. 2 years is nothing, really, and judging by the size of the fish I doubt it is at the point where an issue should be contributed to old age.
