I'm not even sure what just happened. I posted in another thread about the diatom problem I've been having in one of my tanks. This is a ten gallon with 7 juvenile (one in.) tiger barbs and five serpaes. And an ivory snail. Yesterday I put in two young male mollies to try and help with a diatom bloom.
I've been doing every other day 10-20% water changes in this tank because of the bloom.
Today I did a 50% water change in my 40 gallon and my 10. While I was filling the 40, I looked over, and saw that all of the fish in the 10 were swimming sideways or on the bottom. I grabbed the mollies and threw them back in the 40. The barbs were looking okay-ish compared to the serpaes. I got my biggest serpae who's one of my favorite fish into my 20 in a different room, where he used to live, and he rallied for a bit. Two of the smaller serpaes died in this time. The mollies were both fine in the 40 gallon. The biggest serpae was no longer rallying, I moved him closer to the filter current, but it didn't help. In the end I lost all my serpaes and at least one barb.
I have no idea what just happened. I've moved the snail out of that tank for the time being. All of the fish were fine this morning. All of my tanks get the same water/water conditioner/water temp. They do have different substrates and filters.
I haven't tested the water since I'm waiting for everything to settle post water change. But what on earth could cause them to go from being fine to dead in a matter of minutes like that? (And it really was minutes. I'd say 15 minutes tops from the time they got new water to the time they were all gone. )
My 40 gallon seems fine (though their water is low since I haven't finished filling it... maybe I won't.)
