Just wondering does anyone know for sure how long rainbow crabs live, I've tried to research it and and I've got anywhere from 5 to 30 years. I've had mine for 4 years now and i'd just like an estimate for how long he's got left. I'm not considering getting rid of him or anything i'd just like to know. Anyone have a clue?
Depends entirely on the setup you keep them in, If you take into account they are truly a land crab in nature and will travel hundreds of miles during their lifetimes walking from pool to pool, and set up their tank accordingly then 10-15 years should be possible,
However with most setups 1-4 years is more common due to unsuitable setups
In the wild 20-30 years is possible,
