Where did I go wrong
Well this story has a sad ending, but I'm hoping I can learn from it. So I want to know where I went wrong.
I've had a 10 gallon planted for years.. it goes through various levels up good and bad upkeep depending on my schedule.. but it has generally been good over the years. It was aquascaped in it's current design about 8 years ago and I was kind of bored with it and wanted to start over.. the last 6 months I haven't spent much time on the tank and so it was a proper mess.. lots of algae everywhere, jungle like. Not good. So I found an inspiration and was all set to start except for the problem of the current residents. There is somewhere between 16-18 lemon tetras in there.(Too high for a 10G I know.. but I had 3 and a lot of java moss.. and next thing I know I had 18). They are a pretty mature group... mostly 2 plus years old.
So that is the background.. I knew doing a full cleaning and substrate change was risky with established fish and expected to maybe lose one or 2. I put the fish and an amano shrimp that I hadn't seen in months in a 2.5 gallon bucket with current water. Took everything outside hosed it all down and scraped all the algae clean. Put it all back together and put my new substrate in(Flora Max). Added the 3 plants I plan to keep and put about 4 cups of the old gravel in some pantyhose and dropped it in.. put 5 gallons of water in .. added the 2.5 from the old aquarium and topped it off. Now not even 45 minutes later every lemon tetra is dead. All laying on the bottom of the tank. The shrimp is fine.
So what could/should I have done different. I have a biowheel filter that I left the same filter in.. a big pantyhose full of old gravel and 2.5 gallons of water from the old tank. I really thought all that combined would have plenty of good bacteria in it and protect my poor lemons.
Pretty sad.. I've killed off one or two fish before like everyone else.. but never 16-18 in one shot.
So like I said.. where did I go wrong?
