Hey there
just needing sum help not to sure whats wrong with my jd we bought him about a mth ago and he has been fine. last few days he just sits at the bottom of the tank and doesn't seem to care about swim in the bubbles (like he has been doing since we got him lol) last night i went to feed him and normally hell attach the food straight away but he doesn't seem to be fussed by it at all i even put my hand in the tank and touched him slightly to see if he move and about 9 seconds later he finally did. Also this morning i have noticed this white sack like thing hanging from him if any one can suggest what may be wrong or what i should do would be a great help as i do not want him to die Ive attached some photos as well .

Thanks heaps.

Test you water, NH3, NO2, NO3 and PH there will more than likely be something wrong there. Looks like he has white spot which is stress related. 9 times out of 10 it's the environment there living in that causes it.
