My fish may have died because of that. I cleaned its makeshift tank occasionally, but since it didn't have a filter, it got dirty very quickly. Perhaps that was the reason.

Thanks for sharing your story. I also enjoy watching tadpoles develop, but when they grow up and become frogs, I prefer to keep my distance. It's amazing to know what you were able to observe after collecting the tadpoles, since you could better observe their development. Although it was a shame they disappeared, tadpoles are great amphibians, and it's quite a sight to see them grow. Thank you for leaving such a kind comment and sharing such a wonderful experience. See you later.😀
