Is your water testing equipment old? have you recently tested for ammonia?
I used both the quick test strips (6 way strip and separate ammonia strip) and the full test kit (API kit that has test tubes and chemicals). I didn't think it could expire but I'll run get new test materials today. Are there test systems you reccomend?
The neons look stressed- all of them. At points their mouths open wide and they appear to be gasping. One with the tail rot ( it does look like tail rot) has erosion of the mouth that is due to secondary bacteria. Most likely aeromonas bacteria.
Gosh, that sounds horrible. 1 of the tetras had his 6th birthday with us in Nov 2019 (based on when he came home from LFS - not including how old he was at time of purchase). 3 of the neons are 5 years old and the others are 3 years old.
How often do you change water on tank?
A month ago we had a Huge infestation of snails. It started as 1 then, then a couple, then many. They came in on plant b/c I didn't quarantine the new plant as I had put corey catfish eggs in our quarantine tank (eggs are always eaten so we tried to grow them separately but failed).
We got assasin snails but they couldn't keep up ever with me removing snails daily. One day, after picking over 100 snails out of the tank (really, the kids counted), in frustration I decided to empty the tank/snails. I know - not a good decision!
The fish all went to different tanks and containers separated by species, same for each plant. Emptied tank completely and got rid of gravel - added sand. Yes - I know this was completely the wrong
Prior to a snail infestation:
Stable tank, everyone was healthy, cleaning routine was easy: weekly rinse of filter floss, tank rinsed biomedia, 1/3 water change every 4-6 weeks when I did a light vacuum the gravel (most was carpeted with baby dragon tears) . Chemistry testing was weekly when my kids record babies, plant and fish growth and behavior patterns. We used only Prime and 1 correct pH tablet at water change. It was a happy little ecosystem.
After the snail removal nuclear option (for past month):
Replace gravel with sand, added back fish, kept plants in different quarantine tanks and buckets for cleaning, slowly added in big leaf plants I could clean. The water chemistry was normal but 1 neon started to look bad. We were doing 50% water change weekly with filter floss rinse 2x week (I tank rinse my bio media too).
Did you experience this cloudiness after treating for fin rot? Did you happen to use erythromycin?
Yes, all problems (cloudiness) were post snail tank change out when we treated for the "fin rot" (a week after snail/tank mistake I made). LFS said to treat with both Primafix and Melafix at same time followed by 60% water changes after 7 days. We never used erythromycin.
I've added API stress coat during and post snail disaster.
I'll go get a new chemistry set today!
Should I move neons (or everyone) to my quarantine tank?
Are they in pain?
Our bristlenose pleco momma does not appear to have laid eggs and she was due yesterday (based on past cycles).
