I'm not saying that it's completely normal, but that does not mean that it is not uncommon. I don't think that the reason your gerbil's tail fell off was because of the jagged area, but because your sister pulled him by the tail. You should NEVER do this. If you do, the tail will either deglove or just break off.

Eggs develop more rapidly (in a few weeks) in warmer temperatures, and more slowly in colder water (up to months).Most freshwater fish spawn in the spring, although salmon, char, and some trout spawn in the fall.ish Spawning.

Research done in 1984 in Texas showed a survival rate of 73%, and a Georgia study, done in 1990, showed a 63.8% rate. Why donât we close the season during spawning time? Speckled trout exhibit a protracted spawning season, lasting from April to September. Females ready to spawn have even been recorded in March and October. Closing the season during spawning would result in a 5 to 7 month closure.
