Bleeding in Leo tank

[kate_dawn97]

I've found blood in my Leo tank twice now. First time was a little bit and around November 28th. This last time there was a quarter sized puddle of blood in my cool hide with both geckos beside it. Neither are injured. What's causing the blood? Thank you in advance!!

Not a clue. Check their vents. Separate them for awhile so you can figure out who's doing it and consider a reptile vet visit.
