Not at panic stage yet - but could be convinced.
I have just noticed some small white spots on a few of my Cardinal Tetra's. The spots are on the fins and the body.
They share the tank with glowlight Tetras, silvertips, Penguin Tetras and about 8 snails of various sizes.
The tank is a Jewel trigon 350. filtration is by a Eheim 2028, no carbon pads installed. Water from R/O changed every 2 weeks - 75ltrs at a time. Planted with some Java Fern, Moss Balls etc.
Can anyone reccomend a treatment to clear this before it spreads too far in the tank?
are your snails pests? or something you want to keep?
If you want to keep them around, then avoid meds with copper in.
If your not bothered with the snails karking it, you can use most white spot remedies, Protozin does work for white spot, but i recommened the normal full doses at days 1,2,3 and 6 but ALSO half doses at days 4 and 5 and it does contain Copper
The only white spot remedy i know that doesnt contain copper is King British WS3
Do increase the temp to 84-86F and also the surface agitation to increase oxygen in the water, this will help speed up treatment which is a great advantage
If its white spots spread out to different parts of fish, its almost definitly White Spot
I've had white spot about x3 or x4 times over the years, never had a fish die to it, always keep the meds in stock, treat early, increase temp, increase o2, no problem normally
Most peeps who have deaths are peeps that dont treat straight away and end up with fish COVERED in white spot
Many thanks for the useful information Fry Lover. The snails were introduced deliberately to help control algae. With this in mind, will I have to move them to a 'holiday' tank whilst the treatment is in progress and then install some polyfilter or carbon to remove the medication before returning them 'home'?
not sure about the carbon or polyfilter, if you want to take no chances then carbon for 12-24 hrs should be enough, you could also do a 30-40% water change
I personally, have used copper based meds and still had snails alive after the treatment, all be it in reduced numbers.
