looking at him/her there is no loss of colour, still quite bright. theres no discolouration at all that i can see or imflamation, his poop i cant coment on as of yet as he/she in hiding most of the time. there may be a bit of, hes not the smallest and hes not the bigist in the tank.
with regards to the tank, water is quite good from what i have been told and read and is as fllows:
PH= 7.2
KH= 6 o/d
GH= >16 o/d
NO2= 0 mg/L
NO3= 0 mg/L
its a 27 gallon tank, theres a little algue problem but was due to over feeding as have tryed to cut down but still give enough to all, i put a little in the loach in questions main hidding place and seems to go...
hope this helps, can post a pic if would help and if i can get 1..
thank you to all
