Bloated Bombina (FBT)

[Annababe]

Hello all, good to see you all again I know I haven't been here in quite a while, I am posting this on a number of forums I used to frequent to see what I can find.

In the last 3 days, Mordachi, an FBT that I have had for almost 2 years now, started showing these bloating symptoms. He was lethargic and un-interested in food on Sunday, but not bloated. Seeing as how I have had him for this long, without issue (other than when I first purchased him-refused to eat for 1.5 months), I am in serious doubt as to it being the chytrid. He is housed with 3 other FBT who are showing no signs of any illness. He has been removed to a sterile tank (water dish, paper towel).

My setup (picture attached)

15 gallon tank (long) with water dish setup
Eco earth substrate
75-76 degrees F
Between 78-90% humidity depending on time of day
Long pyrex cake pan (9x12?) for water dish (water changed daily)
Small water dish on hammock
Treated water sat for 24 hours before use
8 hour UV light cycle (7 am to 3pm)
Regular diet-crickets dusted every other feeding (about 6-8 day interval) with wax worms as occasional treat
miscellaneous river rocks, plastic plants, decoration
Complete tank clean once a month

I am currently treating him with 2-3 drops baytril on his back daily and 2 drops metronidazole.

Can anyone surmise, other than chytrid, what this could be and could I be doing anything else for him at this point.
