I only have a 29 gallon tank, which would be alright if he was a PP, but I've heard at least a 40 gal is recommended for Es.
And plus, he's the only E i have so a species buddy is advised.. But two Es and two PPs in a tiny 29 gallon?? When does it become overcrowding? I'm nervous about having even one E in the tank, I don't know if having two would be safe. But at the same time, I don't want him to be lonely.
Anything is better than the conditions his previous owners had him in but I don't want to stress the poor thing out and definitely don't want him harming my other crabs.
What can I do to keep him happy and prevent any unwanted incidents? Will he be okay without a species buddy and in a 29 gallon?
