When does a ray drop it's sting?

[Bassrutten]

Hey

Interested in how this works. Is there a specific time they tend to do this? or is there signs I should be looking out for?

Cheers

Anywhere from 5 months to .. who knows, maybe as much as a year. It seems to be at least partly related to how quickly the ray is growing. Usually the old stinger will turn white around the base a few days to a few weeks before it's dropped.

5-6 months depend on the feeding amount you will see the old barb began to rise for the tail for the new barb to grow in.
