I have 2 African clawed frogs in 15 gallon. One was bloated so I moved him to a 2.5 Gallon tank with anti-Bacteria stuff and aquarium salt.He is staying the same bloated though. He didnt eat for about a week but Today he accepted a cricket. But an hour or so ago he regurgitated the cricket than a minute I go I noticed we was puking out this black stuff. I was gross but I am very worried. There is a herp vet 2 an hour away and it cost 60 dollars for him to heal my frog. Please help! What should I do? He is around a year old.
