Wow, really interesting!! When I first read the chart, I interpreted "crash" as a tank crash, i.e., total loss of the ecosystem and a need to start over. We've had a few cases of "butt burn," etc. on the forums but to your point, not a major concern from my own casual observation. Of course it also depends on the type and species; i.e. a bimac and a cuttlefish are going to behave very differently... I think tank owners (and the industry at large) tend to get species that are less likely to wreak havoc in a tank, which is why nobody keeps squid, for example.
- but yes Reef Central is awesome! We have coexisted symbiotically for as long as I can remember.
