My male marble has suddenly stopped eating, and has become lethargic and gaspy, he has the front of his disk raised and appears to be sucking water under his disk. My female and all the other fish are fine. Ph = 6.2
no2 = 0.0 NH3 = 0.0 no3 = 10 ppm temp 28 celcius. He is in a 220gal with a ngt, 2 gars, an aro and a female marble. Did a 50% on sunday as per usual, and i did a 25% today and cleaned the filters.
any ideas what it may be? im very worried it is totally out of character to stop eating.

cheers for any help

How did you treat the tapwater? British water suppliers are now adding chloramine as well as chlorine. I have also stopped doing water changes on weekends as I live in a tourist area and they add extra at weekends , especially during the recent hot weather. My female motoro will sometimes show signs similar to what you describe , could easily be mistaken for ph flux. I now use aquasafe as well as an hma water filter and this has stopped occuring. my flower ray( supposedly sensitive) never shows any stress symptoms.

Just my thoughts. Worth looking into.
 
Thanks, i use aquasafe to and mix it in a 50 gal drum first and leave it stood with an air pump for a while before i add it to the tank. Surely if it was the tap water id of had this problem before?

thanks Angus
 
My first thoughts were the same as Sam as long as your test kits are reliable.

Other areas to rule out are voltage leak in to the tank - do a search to test for this with a multimeter as I would hate to advise wrongly but I think you use the earth socket and the other probe in the water but take care!!!! - this could be caused by a faulty elec item??? RARE

It could be illness / virus have you added any recent fish or fed live foods?

Is the PH moving about much?
 
The water is all good, i did a 25% today and took all the decor out, behand my basket of coral sand (need to buffer ph as is low and my water has virtually no hardness), the sand was quite deep here and was smelly ive moved it all around and left the decor out so the fish can keep it turned over. Could this area of stagnation have caused something irritant to him? hese picked up sinse i did this and has eaten some massivore?
No new fish in sinse febuary and never feed live.

cheers Angus
