Sorry, omgitslph, I just got here. Poor Lando (I'll pass by the total SW geek name for now
). First things first.
Generally, I find it's actually okay to feed pea as long as it's a very small amount, like the size of a fish pellet. Also, the best way to prepare the pea is as follows:
fresh or frozen NO SALT ADDED pea. Put one pea in boiling water for 2 minutes, then put it in ice water for 1 minute. Cut in half and take a small piece from the middle, a piece the size of a pellet. Feed that. You should be okay.
Secondly, that he pooped but is still bloated leads me to think he may have parasites. See if you can find Jungle Labs Anti-Bacterial or
Anti-Parasite Medicated Pellets. Continue the epsom salt treatment and keeping him warm but see if the pellets will help. If he does not go down in size, it may be time to try medications.
