Super easy solo tame strategy is to get a dunkleosteus with a decent saddle since it gets a 75% dmg reduction even a low lvl dunk works well. Just swim up to it on the dunk, have it on follow and when the squid grands the dunk just hop off put the pearls in it's beak and swim straight up. The squid has a ceiling just like the mosa and plesi so it will only follow the dunk a short way. Tamed a 140 squid with a lvl 40 dunk and never lost more than 400 health.
