Cloudy eyes

Thx all bros for your replies. After more than a wk from this post, here's an update:

The cloudy eyes appears to be recovering slowly. Still a bit of cloudy eyes. The SDs have white spots too & recovering also. All I did was increase amount of salt added over a few days, no other medi added. Didn't do any water change at all during this period. I intend to wait till they all recover before doing a water change coz worried temperature change due to water change may make it worse.

Also I realise that the tank water temperature is nearer to 29-3 degree c rather than 33 degree c as previously posted. This is because I used another thermometer to compare & realise the one I'm using is not accurate. In fact I've used 3 diff thermoeter to compare & all 3 show different reading in the same tank! That means I dunno which is accurate. Think gotta calibrate all thermometers to find out the correct temperature reading, ie. put them in ice for zero degree c reading.

Thx bros Anthen & Branong. I didn't change water coz tank low bioload & clean. I didn't quarantine the fishes too coz my tank is 2.5ft height, 5ft long extremely difficult to catch the fishes (tried but gave up). I try not to remove the fishes as far as possible coz gotta carefully remove the lightings, carefully remove glass covers on top, try very hard to catch the affected fishes as they dash around the tank.. hand not long enough to reeach the bottom.. .
