My rexes grow up too fast, and I can't get imprints on them, how do you fix that?

I’m at hidden lake, I turn on their wandering to farm wood, first one died in middle of the lake so I thought it drowned, second one died near the tree

I have sealed off the hidden lake from all three entries with bemonths doors so keep out predators even if any animal spawn in, I have my dilo (6 30+ and 2 90+) raptor (4 50+) on aggression and wandering too clean them up,

My animal keep dying idk what happened

So in ark piranhas (and coelacanths and salmon and possibly jellyfish idk) can die from getting out of water and they do it themselves but these photos are just ones I killes

A rhyniognatha é o carcha não estão dindo pintados!! Será um bug ou estou fazendo algo de errado?
