I have a problem, my Swordtail fry are dying always when they are around 2 weeks.
I have 10 gallons with 100 fry & feeding Hikari First Bytes & do 90% water change every night. But I also don't have a filter.
1. Food - Hikari first bytes
2. Filter - No filter
3. Fish dying at 2 week
Previous time, I had the same issue & almost 50% died, which made me so sad. At that time I was changing water only every week. So this time I'm changing every day. But still same result.
Is it due to a Ammonia hike during the day time (until I change water in the night)
