Sorry that your frogs are experiencing bloating. Fortunately, it is a soft bloat and fairly easy to treat. The frogs have a fair chance of recovery if the treatment is started now. Follow the instructions in Jenna's post and continue the treatment until the frogs return to normal. One good thing about clawed frogs is that they are salt-tolerant. Since several frogs are bloated, it is likely an environmental problem. Please give us a summary of your tank conditions and we will be happy to advise you so your frogs can have a long life. Thanks!
