They are hardy but if your tank is overstocked and power is out for hours. Trouble is bound to happen. Oh yeah only 2 of the OG's bichir survived, one of them happens to be a 20 year old endli (20 years this year).Yeah I guess that makes sense.They just seem so hardy though. The endli I had back in the day survived all kinds of bad stuff. My step dad would kill power to my room because he didn't like the lite humming sound of the filter. It was a small house and he took my door off because he said he didn't have a door growing up and it'd be good for me. But then he could hear the tank.....Anyway I'd really like to hear about a 20-30 year old Bichir though.
CDM's 20 year old endli.
