im unsure of wot is wrong as im no expert but i would suggest to ur friend to seperate the frogs if he thinks there is a problem. did he quarantine the new frog before introducin it to the tank? this should b done with all new frogs. is the frog eatin and poopin ok? i know u say lack of apppetite is one of the symptoms but puttin the sick frog into a seperate place to eat would b a good idea to find out if it is actually eatin or not. it may b that he is just not seein this frog eat. wot does he mean by 'actin odd'? as far as im aware a honey bath will give the frog a sugar boost and shouldnt b done often. i hope hes better soon
