Yesterday, my guppy gave birth to twelve small fish, but today, I observed that several tails were bent in front of the jar, and the thorns were also bent. What should I do?

In the process of feeding, it should be noted that in the process of growth, if the feeding tank is too small, small fish often turn around and swim, and their spines will bend. This situation can be improved by replacing a larger cylinder. But it's best to avoid it.
