Oh no! I have 7 dead tilapia! I am not sure what caused it. PH is still low at 7.6 and ammonia is still within safe range. I added some crushed egg shells into the gravel 5 days ago, but it hasn’t changed PH yet.
I only changed a few things recently. It could be any of these or all of them:
I removed 5 large feeder comets, I suspected that they were eating a lot of the food. I fed them koi pellets and fish flakes once a day around 5. sometimes I’d feed them a little bit in the mornig, but not usually.
Its been hot lately, termites have fallen into the fish tank. These cant be bad for the fish, can they?
I added a bucket with holes and some of the duckweed into the hydroponic/water tank weighted down with some red cinder I had just washed the day before, hoping that the fish water would make the duckweed grow faster. I removed it.
I used some copper hinges for the fish tank barrel, I meant to change it, it was starting to rust. I took it out, wiped it down and used zip ties to serve as hinges.
I had a steel clamp holding down the hose down onto the pump I had. There was no rust. I swapped it out with a better pump that fit the hose.
I changed a few gallons of water, I do not have a lot declorinated water standing by, but have more dechlorinating now.
I hope the remaining 5 fish make it, but don’t have high hopes. I have the dead fish on ice. They range from 4 inches to 2 inches. I will try to cut one open tomorrow and see what I can find, but I didn’t do that well in biology, back in high school 20 years ago.
