I just woke up this morning and found 8 dead fish in my 29ga tank (3 Bosemani rainbows, 1 Red Irian Rainbow, 2 turquoise Rainbows, 2 Green Tiger Barbs). The only remaining fish are 2 female Red Irians, a baby pleco, and a SAE
. The tank is heavily planted, eheim ecco 2330 filtration, Hagan CO2
system, massive light, a FLO rotating deflector on a powerhead and has been running for over 2 years.
I did do a 10ga water change yesterday using Amquel, a little Dr. fish Salt and some Natural Aquarium vital added later.
Tank parameters are Ammonia, Nitrites-0, ph
-7.0. Nitrates are deceptive because of the Natural Aquarium vital addition.
Some fish were floating and some not, many with mouths wide open. The still alive fish look fine-no problems.
HELP, I don't know what caused this- All of these fish were show fish- best I've ever seen. THey were raised in my 125ga tank until 2 years ago.
