Karen B. Posted September 23, 2021 Share Posted September 23, 2021 Greetings My false julii corydoras are breeding like rabbits. At first I tried collecting the eggs, having them hatched, raising the fry but my success rate wasn’t that high and I do not really want to breed them. So now I just let things happen in the aquarium - some eggs hatch, others get eaten, some little fry are hunted down by my honey gourami, etc. That’s all fine by me. But today I found a few weeks old baby dead, and that’s bothering me. Is it a common thing happening/natural occurrence that some even when they reach a couple of weeks (so no longer prey for anything in the aquarium, free swimming, eating with everyone) will randomly pass away or is it due to a mistake I may have made? That’s what bothers me the most in this hobby. Rarely having a clear answer and then feeling really bad and being unable to correct a mistake I may have made. It’s a community tank (1 honey gourami, 8 chili rasbora, 7 adults cory, 8 babies - letting them grow then I will give them away -, and up to 5 oto - I never see them, so not sure of the number anymore - and 4 nerite snails. 20 gallons high, planted, HOB aqueon quietflow 30 and an aquarium coop medium sponge filter. temps at 75.5, pH about 6.6 and kh at 0 - I did buy the kh buffer to raise it. Will use at my next WC this weekend. Gh is at 300 (on the aquarium coop test strip), no chlorine/ammonia or nitrite. For the past many many weeks I was surfing on 0-10 ppm nitrate. So I was only doing very small WC, no gravel vacuum because I had bad experience sucking up some fries, and only topping the evaporated water. I did that last time monday and added some easy green. To my surprise right now my nitrate is at 50ppm. Can it explain the death of my baby cory? Should I hurry up and do a WC right now or some of the nitrate might be because of the easy green? I also add daily 2ml dose of excel because of my black beard algea… I spot treat, could I have accidentally spayed it on the baby? I also added some activated carbon for 2 day (the one that is in the cartridge sold with the filter) because I wasn’t sure if I accidentally put my hand in the aquarium while having some residue of lysol wipes on my hands (they were washed but were still smelling the product.
