We are glad to learn you have converted from 'lurker' to member Welcome !

They are beautiful frogs; entertaining and always looking for their next meal...and a date. Ha !
I am sure you are aware these toads appear to have the ability to change their colors a little, based on their environment.

It certainly sounds like you have done your homework!
Can you post a photo of their enclosure We would love to see it. If you start your own FF album your photos will appear on the "Home" page.
Try to watermark your photos, if possible----as we like to post nice photos on fb as well

I’m sure you also know a 50/50 ratio.. is the usual ......... or at least a 25% water coverage is necessary for them to be happy
The water does not have to be deep. They prefer to sit rather than dive or completely submerse themselves. Water quality is really important as these toads seem particularly sensitive to poor water quality. Regular water changes are imperative ( it’s best to have a strict schedule like one would if keeping tropical fish) . Removal of chlorine and chloramines is a must.

They will appreciate some real plants in the water.....
Pothos works well; the plants will help the water and will provide an egg-laying location for females.

There are lots of FF members that care for fire bellies….hopefully more people will chime.
I don’t keep fb , so I have not observed them long enough to comment on their ‘happiness’.
Consistent care, maintenance of their environment, and on-going observation will lead to your developing a keen eye on evaluating this.
It is definitely a learning curve.

As for a cricket tricks..... I'm hoping members can share some tips with you
You don't want them -dead- in the substrate.
