Please read (fire bellies)

I have 3 f.b. newts, two of them for about 9 months. About 3 months ago I bought 2 more newts in hopes of socializing them more as 1 newt is always in the water & eating, the other always out of the water and not eating. 1 of the newts ( the bigger of the new 2 ) died 2 weeks ago. The Dr. said a sinus infection & gave me meds. that really did help, but it passed away anyway.
Now the newt that never ate anything is in/out of water eating. The other "new" newt now has what seems to be an irretated "wet" spot on its shoulders, which is weird because the rest of it's body is dry. It really doesn't eat either and is very small ( he came that way )
Please help if you can I really don't trust the Vet with my newts anymore. It's too expensive too. My newts are in a 10gal. tank with a filter and turtle dock and eat tubiflex worms. Any help is appreciated..... Thank you

Hi Richkat,
if you say the size of the smallest newt where you can help!
I have no idea how much is 10 gallons to liters, but I suspect it is too little for 2 or 3 newts!
But I leave you a hint, where you can pepper it with water, try not to let it dry!
Other advice, trying to give them earthworm, is the most complete food that they can give.
I have helped!

The tank size is OK (10 gallon =~38 liters). I'm sorry that your vet has not been able to help. Your best bet is to stick with good solid husbandry. What is the temperature in the water? It's essential that you find some kind of food that they will accept while on land. Options include live tiny crickets, pieces of earthworm offered on a toothpick, etc. See the FAQ linked in my sig line.

Depending on the type of filter, you might want to remove it. CFB are a pond-type newt and don't do well with current. Also, some filters heat the water, and this is counterproductive.

For the "wet" spot on the skin, you can try treating it with Neosporin (the kind w/o pain killer). Silvadene cream would be better, but you'd have to get that from a vet.

Keep in mind that the newts you bought have been taken from the wild and shipped across the world. And they are not a species that takes that kind of thing easily. A lot of them arrive in a condition where they never adapt to captivity or are too badly treated to recover. Getting healthy captive-bred newts is an option you may want to consider in the future.

Do you have a photo of the wet spot? As when the newts release their poison it becomes wet on their necks? I'd like to see a photo to rule that out (although I dont think that is what it is).
