I'm pretty sure these fish ejaculate whenever they see someone of the same species as them.
NOT FISH despite the name. Cephalopods are molluscs like snails! They are pretty smart and can have somewhat elaborate mating routines, and most species are somewhat careful about sperm sac delivery AFAIK. Lonely prisoners are not good behaviour models.
Very intriguing! Thank you for correcting me!
Cool, and if anyone wanted to dive into the cuttlefish rabbit hole, er, den, 10/10 would recommend any reading or documentary about them. Astonishing visual communication and camouflage, curiosity, problem solving, and more weird biology.
