I havnt, but my friend have, dont know the time it took to lay a sac but once it hatched, he let the slings and female live in tge same tank untill the offspring was large juveniles, subadults. I guess the clutch wasnt very big! Less than 100 i think?
@Venom1080 I actually paired the genus (H. gigas) for the first time last week... was going to suggest whoever has the sac drop first must send the other some slings but I see you're in Canada. Anyway, we shall see. Good luck with yours and you should post some pictures when you have updates!
