Hello everyone. I purchased a toad 3 days ago. Went to PETS MART today to purchase another one. Within 15 minutes of adding the new one to my tank, the old toad jumps on the other's back and will not let him go. The newest toad tries to get away, but flips over in the process because he can not get away. I do have a video of them doing it, but not sure how to post it. I could email it to any of you, if it would help. Is this normal behavior or do I need to take 1 of my toads back for a refund? Thanks!
