I got two tomato frogs in a 36" long by 18"D terrarium. I kept them in moist ecoearth, one was a young male about 1 year old the other a female, much bigger that I adopted called Tang.
Fireball has had a good appetite and a good personality all the time I've had him. I've kept them in a shelved cabinet for over a year. Their level on the cabinet didn't have a lot of height, which I didn't think would be a problem. Because I had only one attachment for the light, (which allow the light to clamp onto the wood on the side of the tank to direct in white light), they shared it with the Firebellies for a few hours a day. They didn't have the extra height because the carpenter messed up when building it for me. So they didn't have UV light on the top, I just dusted their crickets and worms with calcium & d3 and a small mix of multivitamins.
A short while ago when cleaning the tank I noticed a small white substance in the enclosure, that looked like a chewed piece of white bubblegum with light blue lines in it. I thought for a moment it was a stomach, I heard of frogs doing that but they both looked and acted fine. Part of the problem is my carpenter build the cabinet higher then I specified and I cannot keep as close an eye on the frogs on the higher level. So I just kind of mist them, give them light and peak in on them sometimes. I threw the substance out hoping it wasn't a stomach.
A week later when I was taking a closer look now that Fireball wasn't so buried in soil I noticed he looked puffy. I washed my hands well and gently removed him into a small moist enclosure to examine him. This what I noticed:
Slightly puffy cheeks
tiny drop of blood by lip
I freaked out and tried to figure out what to do. My next few days were 16 hour work days between work and my placement from college. My roommate took him to the vet and they determined that what he coughed up was likely an infection in his stomach. They said he had soft jaw, which they said was due to lack of UV light. From what I've read tomato frogs do not require UV light. I thought the food dusting was enough for them, Tang has showed no issues and I've had her 2-3 years. They also thought it might be the pet store cause frogs often have parasites from many pet stores they said. But my PetSmart was a vet look over all the frogs, but i guess its still possible.
They said he needed day to day in house intensive care, but because he was young they believed he could make a full recovery. But I can't afford full day to day care so I had to surrender him to them. I thought it was best for him to stay with them to get what he needs so I paid the vet visit bill and now I have just one Tomato frog.
