Tank size: 14 litres (hospital tank). Normally 15 litre section of 30 litre tank.
pH: 7.2
ammonia: 0
nitrite: 0
nitrate: 10
kH: 90-100
gH: Approx 220
tank temp: 27 C
Fish Symptoms (include full description including lesion, color, location, fish behavior):
Split fins, very thin, very pale and grey, lying on the bottom more but still active, still eating with gusto, still interacting with me and his environment. Started to darken and change colour from the day I got him but I assumed he had marble gene due to his unusual colouration. Very small fish - I have had him for 4 months and he is still as tiny as when I got him at 3 months old. Have not seen him poo much.
Volume and Frequency of water changes:
Between 25% a week and 50% every two weeks, depending on how busy I am. Nitrates never go above 20 (usually 10) and pH does not change.
Chemical Additives or Media in your tank:
Zeolite and carbon in filter.
Tank inhabitants:
One other male betta, who seems in excellent health.
Recent additions to your tank (living or decoration):
He's had a few tank changes since I have had him and his darkening has been consistent throughout. However, recently he has had a tank change (just before Christmas), new plants (live and silk - 1 week) and a new tank mate (divided tank - 3 weeks)
Exposure to chemicals:
Unknown. I am careful about deodorants and air-freshener. Should not be a problem.
Digital photo (include if possible):
